I have posted this in the newbie forum also, but wanted to get some more detailed questions and thought it appropriate here, too.

I had some general questions about finally starting a Saltwater/reef tank. I have a custom built 150 gallon tank with artificial rock walls (permanently attached) on the back and two sides which is set up as a freshwater tank right now. I plan on eventually moving my current Cichlid out and breeding him in an indoor pond setup. Anyways, when I empty this tank it will have about 125 actual gallons of water including the sump wet/dry (which is a 26 gallon Rubbermaid). I plan to remove the wet/dry filter capability and probably just install a Protein Skimmer in the sump. I’m also tossing around the idea of using a spare 55 gallon as the sump (if I can fit it under the tank) and installing the PS in that. Either way, I’ll be pushing about 600 gph through this sump. I already have a Filstar XP-3 that will act as additional filtration if needed (any opinions?). I can add up to two powerheads, one on either side of the front glass for additional water movement. Is this going to be enough water movement for a reef tank? Right now I have the sump pump (600gph) + Filstar (350gph) + 1 powerhead (350gph)for a total of 1100gph, to which I can add one more powerhead (say another 350 or maybe more). So around 1100 to 1500 gph for circulation in a water supply of around 125 to 150 (using the 55 gallon as sump). I’ve got only 220 watts of CF lighting over this tank (which is 24” deep). This lighting has been superb for my FW planted tank, but I’m wondering about it’s ability as reef lighting. It may be possible to add additional lighting in obscure areas of the Hood, but it was custom built to hold this lighting.

Alright, now to what I plan to add. I already have artificial rockwork over three sides of the tank, so this will probably work well to support other rockwork and to use as a starting “wall”. I do plan to buy about 200 lbs of live rock to go into this tank. Probably several different types to maximize coralline algae and other critters. Should I go with pre-cured or not? I hear that you maximize your critters and algae with un-cured, but there can also be problematic creatures hiding. Also I have read that I need to do my own curing for a couple of weeks anyways, because of natural die-back. I plan on using some Limestone I already have (pretty large stones) as some of the base-rock, and maybe I can get away with less actually bought live rock. I also plan to buy some live rock and add this to the top of some other normal sand. Can I use regular playsand, or do I need some other type of marine substrates? I’d like to get a sandbed up to 3 or 4 inches ( I have heard many debates about the usefulness of different substrate ideas, but please discuss with me any of my options with at least a minimum of 2 inches of sand or more. I do not want to mess with a plenum or such, just straight substrate. Ok I can probably add some sand to my sump as well, to keep a safe area for additional life and as a refugium. I can add lighting below my tank for the refugium also, but don’t want it to be extremely intense.

As for inhabitants, I would like to try some of the easier soft and maybe some hard corals. I don’t want anything that is very sensitive and difficult to grow. Also, remember that I don’t have the most intense light for a reef tank, so the low to moderate light requirements is probably appropriate. Any ideas on corals would be great. Please list some that are easy to locate. Oh, by the way, something I read recently was about deepwater corals, that don’t have zoozanthella and don’t require any light, but are still extremely bright red. You have to worry more about direct feeding these corals, but that would be worth it to get something as interesting. Ok, now for fish…..here goes! I know this is going to be the tough one, but I’m sure it’s possible if someone knows how to set up and mix fish with it. I’ve been wanting a Porcupine Puffer for a long time as a “showpiece personality pet”. I know they tend to be a bit aggressive and can tear through some inverts, but is there a way to mix them with corals and a few of these other fish? The other fish I’m interested in are: Sailfin Algae Blennie, maybe 2 Ocellaris Clownfish, and perhaps a Blue or Yellow Tang? Alright I looked at a compatibility chart for these fish (generic, I know), and all of these fish seem to be compatible, with a “caution” listed for Puffers with Corals. Now to be honest, I’m not interested in the Clowns without a coral to hide in. I’m not interested in any fish that are obviously going to be huge problems. I had previously wanted to just house a single Puffer in this tank with just live rock, but I really like the look and want to try my hand at corals too. I also am interested in these other fish. This setup is going to be a showpiece (it actually already is a planted showpiece in my living room) so I wanted a change of scenery that would be beautiful and have some fish with personality. Any other info would be great, thanks for listening.
 
any mushrooms, zoos, leathers are easy corals to start out wtih.

as for the pufffer, if u have plenty of rockwork, and many caves and hiding spaces for the other fish to hide in case the puffer gets a little crazy, they should be fine.
 
What about something to stir the substrate and keep it turned over? I have read that I need some critters to do that with a deep live sand bed. Any input?
 
A lot will depend on the puffer. Most will ignore other fish, but crustaceans of any kind are on the menu, and stinging corals should be avoided--they tend to swim in and get stung.

For rock--what type of limestone is this? Some is highly porous, other types are not and won't be beneficial.

Turnover sounds good, and with the lighting, you'll be able to support a variety of softies, but I wouldn't try LPS for a while. On deepwater corals--not a good idea. Chilies are perhaps the most commonly available deepwater coral, and even with daily feedings, they die. Not a good choice. If you want a variety of color, look into sponges--not as sensitive, easier to feed, variety of color and shape.
 
I appreciate all the replies.....thanks. I have been stewing this over all last night and today, and I've pretty much settled on the idea of leaving my current FW planted tank as-is! I was thinking about it and realized that by the time I remove all the stuff from the current setup, get new lighting, adjust the filtration, and build a new Indoor pond for the Cichlid to breed, I may as well just leave him where he is and set up the Indoor Custom Pond as my SW Reef setup. The plan so far is to have it on a solid foundation off the ground about 2 feet, then I'm going to build a Plywood tank that is (right now I'm looking at) 5' x 8' and 3' deep. This setup will have 2 sides that have glass installed and it will basically be in a corner for the other two sides, with a small access way behind one of the sides. I think for a "sump area" I'm just going to section off about 1/4 of the tank (far back corner) and use that as a refugium/sump. I'll place the Skimmer(s) in the sump area, and probably the other equipment as well. I may do a plenum in that area and just a 2" to 3" finer-grained substrate in the main area. I'll drop some Pendant MH lights from the roof (probably 4) and build some fancy additional CF lighting holders for the actinic lighting.

Obviously, I'm going to dump the whole Puffer idea, and just stick with a more traditional reef population. One thing different is that I will probably build my own reef and just buy some uncured Live Rock to bring in some micro fauna and buy a few bags of Live Sand to seed the rest. I will build my own rock using the method for "aragocrete" at www.Garf.org (or .com) -can't remember. They also have some seeding kits you can order. I'll probably also get at least one rock locally, just to diversify my setup. The overall gallons of this setup will be about 654 gallons, of which about 490 will be the display area (with a 164 gallon refugium/sump). I figure that I will have spent as much time and money transitioning the other tank and placing my FW fish in this tank, as I will just making the Pond/tank the Reef display.

How much can I expect to spend on Supplements and chemicals every month (or week) in a tank this size? I know that many corals and inverts need additional supplements. Also, is it a problem to use silica based playsand and mix it about 50/50 with Argonite sand. I'm just looking for a way to cut costs. Any other cautions or input? Thanks again everyone.
 
Basically what you should do it write up a list and post it here of everything you want to add to the aquarium so you can get diffrent opinions about what would need to be supplimented. In terms of sand, you dont need any aragonite and go with just silca playsand if you want, or 50/50 works as well.
 
Ok, I'll do that. Give me a day or two to create a picture to show the layout and also a list of ideas.
 
It actually wasn't as time-consuming as I thought, so I'm going to try to post the diagram here. Well, it's too large as is, so I'll post it in my webshots folder and give a link:
http://community.webshots.com/photo/300483461/405779616kCahXn
That should work. Let me know if there is a problem.

Now for some specifics I have listed in the diagram:
-Metal Halide lamps will be 250 watt each (preferably Dual-end bulbs). I have 4 of them evenly spaced in the main tank area for the most part.

-The CF fixtures are 2x96w for the 3', and 2x65w for the 2'. All have Moon light LED's. These are over the areas with the highest rock points so they should still be useful. Should I drop these and just stick with getting more MH lamps? They cost about the same as another MH lamp, anyways. I was just trying to have some ability to use actinic blue lamps.

-I also plan on doing several fancy things to the substrate bed to make my maintenance as simple as possible.
1) I plan on using a Plenum with eggcrate and a blend of aragonite and silica "playsand", with some crushed coral, as well. The sand bed will be about 2 to 3 inches total, with 1" below the eggcrate. Because I will use Aragocrete, I will have very little rock surface sitting on the sand bed, which should allow the plenum to operate at peak performance.
2) I plan on integrating an undergravel Jet system to aid in water current and also to simplify my work of trying to clean out junk from under the Live Rocks (there will be alot). These should help keep food and waste in suspension and help corals get their food, and waste filtered out to the sump.
3) I'm also considering treating the plenum as a UGF for a month or two to get it nice and seeded with life. After that I will cap or remove the standpipes and it should be a quick jumpstart for the plenum. I got the idea from Garf.org, in the "bullet-proof reef" articles.

- I will add several powerheads to keep dead spots from forming. Otherwise 2 decent Skimmers in the back of the sump will be my only real filtration to export waste, other than water changes. Everything else is for water movement only. I will have a plenum, plenty of Aragocrete and a few real Live Rocks (for seeding), and of course a live sand bed in the tank itself and the sump. I probably won't use a plenum in the sump, but rather just do an extremely thick 5-6" DSB in there and see if I can get good results from the dual-action plenum/DSB. Another question about the Refugium.....should I raise the bottom up a bit? I can make this area more shallow than the rest (which will be either 36" or 30" deep). Another idea for lighting is to substitute a MH lamp over the sump area to add more intense lighting, although less evenly spread out than the CF pendant. Which do you guys suggest? That's all my brain can take right now. If I've forgotten anything, then let me know. Pleae let me know how well thought out and feasible this setup will be and your opinions on how to improve it....thanks.

I'd go ahead with the CF for the actinic--the MH won't provide that spectrum, and it is beneficial to corals.

The plenum runs on anaerobic bacteria--I don't think runnning it as a UGF (or encouraging any water flow through there mechanically) will be at all beneficial. The oxygen in the water will prevent the bacteria you want! By running it, all you'll do is risk putting more solid wastes in there--not a great idea--and delaying the development of the anaerobic nitrifiers.


For the sump--on a tank that large, I would set it up to be lighted opposite of the main tank, and pack it with macro algaes. This will help stabilize the pH, as well as supplementing nitrate removal, and provide a great breeding ground for pods and micro fauna.
