6.0 General Catalogs
Here is a list of non-aquarium related catalogs that have items
that may be of use to the serious aquarist and DIYer.
-
AIN Plastics 1-800-431-2451
-
A nationwide plastic supplier. They have about a dozen outlets
and also ship orders. The catalog contains info and specs on many
types of plastics that are useful for DIY aquarium projects. They have
a $50 minimum order.
-
C.F. Bowman & Co.
-
38 Addington Court,
East Brunswick, NJ 08816;
PH (908) 390-6436,
FX (908) 390-6438
C.F. Bowman & Co. I heard of by e-mail, but I later noticed their ad in
FAMA. Their prices on acrylic tubing look very good, at least; a 60"
long 6" od 1/8" wall clear cast acrylic tube is $35.75, which is about
60% of what I paid. I didn't find extruded tube, but they do say to call
for items not listed. They are ostensibly wholesale only, so you may
need to give a company name. They also have a $50 minimum order.
-
C and H Sales Company
-
P.O. Box 5356,
Pasadena, CA 91117-9988; or
2176 E. Colorado Blvd,
Pasadena, CA 91107;
(213) 681-4925 (LA),
(818) 796-2628 (Pasadena),
(800) 325-9465
C & H sells a wide collection of surplus and used equipment, ranging from
fans, blowers, pumps (water, air, and otherwise), electronic components,
motors (ac, dc, gearhead, stepper), solenoids, laboratory glassware, chart
recorders, and tools through stranger things like gyrocompasses and a bit
of defense electronics. Prices vary but are often quite good. For those
in Southern California, their store has lots of odd items in quantities too
small to include in the catalog.
-
Cole-Palmer 1-800-323-4340 or 708 647-7600
-
A huge catalog of test equipment and related industrial hardware.
Like Markson, much is beyond the need and budget of a hobbiest
but much is not. One of this FAQ's authors gets his lab sized DI
cartridges from Cole-Palmer.
-
Grainger Industrial 1-800-323-0620
-
A nationwide chain of wholesalers of industrial needs. They have
many stores in most states. There is probably one near you. They
have a huge catalog of all sorts of things for DIYers, float-switches,
ballasts, tools, you name it. They are a wholesaler so they
technically won't sell to individuals. If you walk in (they have
a counter just like any retail hardware store) and pay cash and give
the name of a local company, they will sell to you. They just need
to have the name of a company to put on the invoice because legally,
they are a wholesaler. You don't need a tax number when you are
paying cash. You can just go in and give them the name of the
company where you work. It is probably a good idea to call ahead and
see if the item you want is in stock.
-
Hach - Products for Analysis 1-800-227-4224
-
A catalog of testing items. This is the next step if you want
better test kits than best kits normally available to the hobbiest
(like Lamotte). Many of their products are not beyond the budget
of a serious hobbiest. The also carry chemistry hardware like
glassware.
-
Herbach and Rademan 1-800-848-8001
-
A miscellaneous junk catalog with all sorts of electronic, mechanical,
and pumping widgets and other gadgets. Also, surplus junk like
power supplies.
A catalog of a variety of scientific equipment, mostly chemistry related.
Many of their items are well beyond the need and budget of hobbiest but
much of it is not.
-
The Surplus Center 1-800-488-3407
-
The phone number is 800-488-3407 or 402-474-4055. Their catalog has a
large number of pages dedicated to hydraulic motors, pumps, and
valves, which are useless to reef keepers because of their metal
construction. However, the selection of electric motors is greater
than that of the other surplus catalogs listed in this document, and
some of these are finding their ways into experimental reef tank
applications.
-
United States Plastic Corp.
-
1390 Neubrecht Rd.,
Lima, Ohio 45801,
1-800-537-9724
US Plastics sells a large selection of basic materials, plus an equally
large assortment of various manufactured items made of plastic and some
related items like fluid pumps. A few of the less common items which
come to mind are clear PVC, plastic tanks up to a few thousand gallons,
ultra-high molecular weight polyethylene stock, flexible impeller pumps,
and plastic welders. Of special interest to the diy'er would be items
like the thickened acrylic cement (IMHO required for the best and
strongest watertight acrylic joints), their rod, pipe, tube, and sheet
stock in pvc and acrylic (where else do you find clear sheet pvc, or
90 degree sweep fittings for lower backpressure?), and the large food-
quality drums for storing RO/DI water and mixed saltwater. The fun of
finding stuff you didn't know existed shouldn't be under-rated either.
7.0 Some Questions and Answers
Q: Can I do this cheaply?
A: No, relative to a similar size fish-only tank. (See cost estimate
section)
Q: What if all I want to keep is Anemones?
A: Water quality requirements drop some (Nitrates should remain under
20ppm NO3-). Lighting requirements are similar to full-reef tanks.
The keeping of clownfish hosting anemones is coming under some justified
ethical review. In nature these anemones are very long lived and have
low successful reproduction rates. This compounds with typically short
(a couple of years vs. potentially hundreds in the wild) lifetimes of
captive anemones.
Q: What are good test kits?
A: Tetra Hardness;
Hach Calcium, Iron, Phosphate - (303) 669-3050;
LaMotte Nitrate, Phosphate.
Hach Test kit details:
-
Calcium:
- Cat. No. 1457-01, Model HA-4P, $47.50, 100 test
Dilute your sample 2:1 (Distilled:Saltwater).
Each drop of titrant will equal 24mg/l of Ca++.
Dilution saves titrant, and yields clearer results
with sufficient accuracy.
-
Iron:
- Cat. No. 22993-00, Model IR-21, $57.50, 100 test
Very important if Macro Algae growth of primary interest.
-
Phosphate:
- Cat. No. 2248-00, Model PO-19, $54.50, 100 test
This test is 2.5 times more sensitive than the LaMotte
test. The Hach is rated down to 0.02ppm, the LaMotte 0.05ppm.
-
Silica:
- Cat. No. 22550-00, Model SI-7, $72.50, 100 test
Not tested by any of the authors of this FAQ. Mentioned
due to its availability and track record of Hach kits.
Q: What about cheaper kits?
A: Kordon Ammonia, Nitrite, low-end Nitrate not bad for gross measurement,
will need LaMotte Nitrate after water is in proper pollution range.
Q: Which Salt Mix is best?
A: Instant Ocean works for many.
Reef Crystal has had reported problems.
Tropic Marin recommended by some.
Coralife dissolves fast, can sometimes be found cheap, but is suspected
of having higher borate concentrations than natural seawater.
Note that all 50 gallon bags of salt are not the same. Instant
Ocean bags weigh in at 16lbs each, Coralife at 14.5lbs each. There
is no magic here, at a given temperature, a bag of IO will make a
solution of higher specific gravity (or more gallons at the same
specific gravity) than a bag of Coralife will.
Q: How do I get rid of algae in my reef tank?
A: There are three types of undesirable "algae" that commonly grow in
reef tanks: long green strands of hair algae, short fuzzy green turf
algae, and brown or red slime algae. Some people also consider fleshy
macro alga, such as Caulerpa, to be a pest as they can overgrow and
choke out soft corals. Desirable alga are the calcarious ones, both
encrusting coralline alga in pink, purple, white, yellow, maroon and
brown, and larger calcarious alga such as Halimeda. Some believe that
any Macroalgae (Caulerpa, Halimeda, etc.) do not belong in Reef tanks.
"Slime" alga is actually cyanobacteria, not an alga. While its
growth is often taken as a sign of poor water quality, its occurrence
is part of the normal succession of a developing aquarium. It is
uncommon for it not to occur at some point. With patience it will go
away all on its own, but there are some things you can do to
expedite the situation and help prevent it from recurring:
Chevron and Mimic tangs are known for having an appetite for cyanobacteria,
as are baby queen conch and some hermit crabs. Adding such creatures
should help a lot. So will innoculating the tank with some substrate
from an established tank that is slime algae free. Apparently such
tank harbor microfauna that consume or otherwise compete with the
cyanobacteria. By innoculating a tank experiencing the problem with a
small handful of substrate (a few tablespoons full will do) from
an established tank without the problem, chances are good that you will
get a starter colony of the desired microfauna. Use of activated carbon,
strong protein skimming, active mechanical removal, strong water currents,
and use of kalkwasser, will also help control its growth. As with most
things associated with reef tanks, don't expect overnight results.
We strongly recommend against the use of any antibiotics, such as Maracyn,
in reef tanks. As a reef aquarist, you spend a lot of effort and
resources to build the bio-diversity of your tank up. Use of antibiotics
is in direct conflict with that goal. At best, it's a temporary setback
for the cynanobacteria, which, like most bacteria, will eventually
build up a resistance to the antibiotic.
The best way to deal with hair and turf algae is not to let it grow to
begin with. Keep the tank dark while it is initially cycling. Keep
nitrates and phosphates as low as possible, and siphon out detritus.
Keep herbivores in the tank. Snails (as many as 1 for every 2-3
gallons) will eat turf algae, and hair algae before it gets long.
Tangs (especially Chevron, Mimic, and Yellow) and many small blennies
will eat many forms of algae. If the tank does become overgrown, pull
as much as possible out by hand. Reduce the light cycle, or if there
is nothing light sensitive in the tank, leave it in darkness for a
couple of weeks. Get more herbivores. Be sure to siphon out their
droppings, which if left in the tank make great algae fertilizer. I
have found that urchins can help recover an overgrown tank, although
they will knock things over and eat any kind of algae, including
desirable calcarious algaes. Large numbers of small hermit crabs
(on the order of 1 per gallon) are very effective at removing and
maintaining hair-algea free live rock - but do little for sidewalls
and glass. As usual, a large bio-diversity with a mix of snail,
tangs, crabs, and other herbivores will do the best job.
Two relatively new concepts are currently getting some attention in
regards to hair algae control: 1) micrograzers and 2) long cycling.
Some are beginning to believe that the small Copepods and other
"meiograzers" have a substantial impact on the quantity of visible
hair algae. The belief is that the hair algae is always there, it's
simply mowed down by the meiograzers to the point where it's not
typically visible. If this is true, then inclusion of some fish, like
mandarins (which feed heavily on this size prey) would be inappropriate
for reef tanks. As mentioned in the Live Rock section of this FAQ,
the patience to allow a tank to cycle for 3-12 months prior to the
addition of most fish (and any non-herbivore fish) may improve the
stability of the tank in regards to hair algae. Although hair algae
will normally bloom during this period, a compensating population of
micrograzers will also bloom. Once the two come into balance, the
normal routine of slowly adding additional life forms can commence.
Q: How do I treat a fish with ich in a reef tank?
A: From Craig Bingman:
- I don't know of any medication for the treatment of marine ich
that is safe to use in a reef tank.
- A pair of Lysmata cleaner shrimp typically can make a large
difference, even in cases where there is an ectoparasite explosion
caused by an incoming fish.
- If there are recurring problems of this sort in a reef aquarium,
the problem is almost certainly a symptom of an underlying system
performance or fish health issue.
The first places to look are:
- excessive temperature swings.
- low dissolved oxygen
- stagnant water conditions
- improper fish nutrition
Some fish that are cyanide-compromised may be too weak and internally
damaged that there is little that can be done to help them.
Use of a quarantine tank is probably the best solution. A small
10 gallon tank with a heater, air-stone, and some live rock for
filtration should suffice. If treatment of a new fish is required,
it should be moved to a similar, but live-rockless, hospital tank
where medication can be administered. When doing a water change
from your main tank, consider using any clean collected water as
source water for your quarantine and hospital tanks. This will help
acclimate your new purchases to the water parameters associated with
their future home.
8.0 Book Review and Comments:
- The Reef Aquarium Vol. 1, A comprehensive Guide to the Identification and
Care of Tropical Marine Invertebrates
by J. Charles Delbeek and Julian Sprung.
1994. Ricordea Publishing, Florida
ISBN 1-883693-12-8
-
Introduces the beginner to the reef hobby in an understandable manner. All
established reef tank techniques are discussed. Even the expert gets a
comprehensive overview. Nice to read, up to date and a must for all serious reef
hobbyists. Vol. 2 will follow.
- The Modern Coral Reef Aquarium Vol. 1
by Alf J. Nilsen and Svein Fossa.
1996. B. Schmettkamp-Verlag, Bornheim, Germany
ISBN 3-928819-29-1
-
This Vol. 1 starts a book series that has all of what's needed to become the
backbone of the reef hobby. In addition to the information value, it presents
an enormous amount of brilliant picture materials. Some of the later Volumes
are already available in German and contain more than 1,000 colored pictures
per book. Vol. 1 gives a description of all techniques for setting up and
maintaining reef tanks. Should not be the very first book for the beginning
enthusiast, but is probably the best x-mas gift for any serious reef hobbyist.
Note that the English version and German versions of this series are in a
different order with some different content:
English Volume 1 = German Volume 1 and Volume 2
English Volume 2 = German Volume 4 (Cnidaria)
English Volume 3 = German Volume 5 (unicellular animals, sponges, worms, molluscs)
English Volume 4 = German Volume 6 (other invertebrates)
English Volume 5 = German Volume 3 (fishes, with extensive rewriting)
- Giant Clams, A comprehensive Guide to the Identification and Care of
Tridacnid Clams
by Daniel Knop.
1996, Daehne-Verlag, Ettlingen, Germany
ISBN 3-921684-23-4
-
The first book dedicated to giant clams. Lots of information about tridacnid
clams and basic information about setting up and maintaining a reef tank.
Whoever likes clams will love the book.
- The Marine Aquarium Handbook, Beginner to Breeder
by Martin A. Moe, Jr.
1982. Norns Publishing Company
ISBN 0-939960-02-08
-
An excellent first reference on many topics. Not reef oriented.
-
The Marine Aquarium Reference, Systems and Invertebrates
by Martin A. Moe, Jr.
1989. Green Turtle Publications, Florida
ISBN 0-939960-05-2
-
The place to begin looking for almost every topic. Discussion of filtration
is exhaustive, though a bit spare on modern Berlin practice (is this
still true in the new edition?). A must buy for every reefkeeper.
-
Advanced Reef Keeping I, A Comprehensive Guide to Setting up Your
Reef Tank
by Albert J. Thiel
1989. Aardvark Press
ISBN 0-945777-01-9
-
Small Reef Aquarium Basics, The Optimum Aquarium for the Reef Hobbyist
by Albert J. Thiel
1989. Aardvark Press
ISBN - 0945777-02-7
-
Some good information buried among dubious advice
and the most wretched editing ever conceived. His
filtration ideas are rather old-fashioned. This
guy sold the expensive equipment that he
recommends, so Caveat Emptor should be your motto.
Thiel advocates one particular way of maintaining reef aquaria. It's
not the only way, and it may not be the best way, but it does work.
The usual advice is for people to read his books, but to do so skeptically.
-
Corals of the World, Biology and Field Guide
by Dr. Elizabeth M. Wood
1983. T.F.H. Publications
ISBN 0-87666-809-0
TFH# H-1049
-
A good reference for anyone who intends to keep
stony corals. Like other books not specifically
written for the hobbyist, it does not discuss the
care of corals. May be out of print.
- Dynamic Aquaria
by Walter H. Adey and Karen Loveland.
1991 Academic Press, Inc.
ISBN 0-12-043790-2
-
This book addresses designing reef (and other) aquaria on
ecological principles. The book is best known for its extensive
coverage of the Algal Turf Scrubber method of water purification. The
hobby remains skeptical of the use of algal scrubbers as the primary
means of water purification on systems that maintain stony corals; see
the scrubber section of this FAQ. However, text dealing with algal
scrubbers is just a small portion of the book. Much of the space in
the book is spent reviewing the established scientific literature on
aquatic ecosystems, in language that the dedicated amateur aquarist
can understand. The statements that the book makes *in the review
sections* are well supported by citations to the scientific
literature, and in this way the book provides a nice bridge to those
who want to begin exploring the scientific literature. After reviewing
a particular aspect of natural ecology, the authors discuss
appropriate ways to model that aspect of ecology in a small, closed
system. It is in these sections that the reader must be more careful,
because the authors often do not distinguish what are widely
established results and what are their unproven hypotheses. If read
critically but with an open mind, the book offers a lot to serious
hobbyists.
-
The Reef Tank Owner's Manual
by John H. Tullock
October 10, 1990. Aardvark Press
ISBN 0-945777-06-x
-
Discussion of filtration is old-fashioned, similar
to Thiel's books but somewhat more grammatical.
Good discussions of individual animals and animal
choices aimed at the beginning and intermediate
reefkeeper.
-
Invertebrates: Tube-, Soft-, and Branching Corals
by Peter Wilkens / Johannes Birkholz
1986, Engelbert Pfriem Verlag, Wuppertal
ISBN 3-921677-14-9
-
Invertebrates: Stone and False Corals, Colonial Anemones
by Peter Wilkens
1990, Engelbert Pfriem Verlag, Wuppertal
ISBN 3-921677-15-7
-
The authors' experience and reputation is vast. Unfortunately
production quality of the English translation is poor, but there is no
other comparable reference. A must buy for anyone intending to keep
corals.
Daehne-Verlag in Ettlingen, Germany, bought all the books from Pfreim
Verlag upon Mr. Pfriem's retirement.
-
Fishes for the Invertebrate Aquarium, 3rd ed.
by Helmut Debelius
1989. Aquarium Systems
-
(An absolutely fascinating speaker, BTW. If you
ever get a chance to hear him speak, do so!) Quite a lot of good
information on reef-compatible fishes.
-
Armored Knights of the Sea
-
Absolutely fantastic shrimp book. Out of
print, gold if you can get your hand on it.
- Corals of Australia and
the Indo-Pacific
by J.E.N. Veron.
Copyright 1986 The Australian Institute of Marine Science.
1993 University of Hawaii Press.
ISBN 0-8248-1504-1
-
The definitive reference book for the Indo-Pacific stony corals. The
original is out of print and very difficult to find. A reprint
run has recently been done.
-
Living Corals
by Douglas Faulkner & Richard Chesher
1979, Crown Publishers, Inc.
ISBN 0-517-53854-7
-
This is one of those big picture
books of corals, but it's the best
one I've ever seen. The photos are
all top-notch, most show large groupings
of a single species. The descriptions
are not with the pictures, which can be
disconcerting until you get used to it.
I believe this book is out-of-print,
though I often find used copies (fairly
cheap!) at a local bookstore.
-
Marine Plants of the Caribbean, A Field Guide from Florida to Brazil
by Diane Scullion Littler, Mark M. Littler, Katina E. Bucher,& James N. Norris
1989. Smithsonian Institution Press, Washington D.C.
ISBN 0-87474-607-8
-
Quite a good reference book describing
various species of algae that are found
in the waters of the Caribbean.
-
Seaweeds of Hawaii, A photographic Identification Guide
by William H. Magruder and Jeffrey W. Hunt
1979. The Oriental Publishing Company
ISBN 0-932596-12-6
-
Another excellent reference identifying
algae found around Hawaii. Out of print.
-
The Manual of Marine Invertebrates
by Martyn Haywood and Sue Wells
1989. Salamander Books Ltd., London
ISBN 0-86101-474-X
-
I'd recommend the Manual of Marine
Invertebrates by Hayward. While this
does not go into a great deal of detail
on anything, it covers every class of
inverts and is good for learning about
what's on your live rock and the basics
of care for different kinds of creatures.
It contains quite a few mistakes, but is a
good reference book nonetheless.
-
Encyclopedia of Marine Inverts by
Jerry Walls,
(TFH, Neptune, NJ: 1988) ISBN 0-86622-141-7.
-
[Compared to Manual of Marine Invertebrates by Hayward] and found that the
later (Wall's book) appeared to have a lot more info. It isn't a great
book from the aquarium point of view but does cover the basics of all the
Phyla. It has a lot of color plates. I was able to identify a number of
Live-Rock ReefCritters(tm) with it.
-
Dr. Burgess's Atlas of Marine Aquarium Fishes
by Dr. Warren E. Burgess, Dr. Herbert R. Axelrod, & Raymond E. Hunziker III
1988. T.F.H. Publications
TFH# H-1100
-
"The big picture book of fishes."
Considered the first book to look marine
fish up in. Second edition has been
published.
- The Captive Reef: A Concise Guide to Reef Aquaria in the Home
by Dana Riddle.
1995, Energy Savers Unlimited, Inc.
ISBN 0-9640147-2-6
-
This is a good starter book for the beginning reef aquarist. The subject
of reef aquaria is treated in an easy to understand format targeted
at the layman. While targeted at the layman there is some information
in the text of interest to the intermediate and advanced aquarist, mostly
in the form of charts and graphs. There is also a chapter on feeding corals
that aquarist may find useful as a starting point for experimentation.
- Tropical Pacific Invertebrates: A Field Guild to the Marine Invertebrates
Occuring on Tropical Pacific Coral Reefs, Seagrass Beds and Mangroves
by Patrick L. Colin & Charles Arneson.
1995, Coral Reef Press.
ISBN 0-9645625-0-2
-
This is a good reference book with lots of high quality color plates of
tropical pacific invertebrates. The text is organized by phylum and each
section starts with an introduction to that phylum. Color plates of many
species in each phylum accompanied by short textual descriptions follow
the introduction section. Many of the various invertebrates kept in aquaria
are represented.
