Cyano

Not neccessary.

Many people have a lot of views but just because you don't agree with someone doesn't mean they are mis informing others. I also happen to agree with Amph as having suffering Cyano myself in the past, did a lot of reading on it and found numerous sources staing that it is in fact photosynthetic.

Source 1
Source 2
Source 3
Source 4

Reducing lighting, cutting down feedings, increasing flow and running Rowaphos, did eventually get rid of mine.

If leaving the lights off is helping the problem,then it is not cyano,it is something else.And from the pics you have posted,I would say it is not cyano anyway.But regardless,the ROWA will help with whatever it is.If you want to return the reactors you bought,I can give you some help in building your own,it will probably save you some money.
When someone is wrong about something they are giving out misinformation.Actuall cyano bacteria does not need light to grow.Just because you read about it on the internet does not mean it is true.I have gotten my information from a Biologist,and when I had cyano in one of my tanks,I tried leaving the lights off for a week,and it took over the tank.

Wow.. sorry, but that is just dumb. I will surely believe stuff I read from UC Berkeley or Wetwebmedia over some random person who got information from a random biologist. What part of this quote are you saying is wrong again? I am not saying turning off the lights by itself will cure a cyano outbreak, but it IS photosynthetic. Personally, I prefer other methods instead of turning off lights to rid cyano, but it is one step to a process that will help slow down the spread of cyano if a person decides that is the route they wish to take.


Taken from the first paragraph from the first link CPD provided. http://www.ucmp.berkeley.edu/bacteria/cyanolh.html
Though cyanobacteria do not have a great diversity of form, and though they are microscopic, they are rich in chemical diversity. Cyanobacteria get their name from the bluish pigment phycocyanin, which they use to capture light for photosynthesis. They also contain chlorophyll a, the same photosynthetic pigment that plants use. In fact the chloroplast in plants is a symbiotic cyanobacterium, taken up by a green algal ancestor of the plants sometime in the Precambrian. However, not all "blue-green" bacteria are blue; some common forms are red or pink from the pigment phycoerythrin.

Whatever their color, cyanobacteria are photosynthetic, and so can manufacture their own food. This has caused them to be dubbed "blue-green algae", though they have no relationship to any of the various eukayotic algae. The term "algae" merely refers to any aquatic organisms capable of photosynthesis, and so applies to several groups.

Actually source 4 is written by Bob Fenner and not just some article on the web.

"Mr Robert Fenner is a marine scientist and a lifelong aquarist, with an active and continuing involvment in the academic, journalistic, trade, and hobbyist sides of aquarium keeping. He is a former marine science and aquariology instructor at the the University of California and in the California State Iniversity system.

Fenner is a regular contributor to a number of aquarium publications, including Freshwater and Marine Aquarium, Tropical Fish Hobbyist, SeaScope, Pet Dealer, and several foreign hobbyist and business periodicals.

He has been a speaker and judge at many aquarium conferences and events, with subjects ranging from cyanide collection of reef fishes to Koi, shell collecting, and environmental, aquarium trade, hobbyist, and scientific topics.

Fenner has worked in all phases of the aquarium business-as collector, wholesaler, jobber, retailer, hatchery worker, designer, manager, and owner. He was a founder and president of Nature Etc., and employee-owned aquatics company in San Diego, started in 1973 and encompassing Aquatic Environments (ornamental aquatics and water-feature design), Aquatic Life Services (custom aquarium system installation and maintainance), and Wet Pets (retail aquarium outlets). He continues as a consultant to a number of public aquariums and aquarium-related companies in the United States and abroad."

Perhaps if you could provide a link to your source 67chevelle, then readers can make up their own minds.

Wow, I am a biologist, too. Degree and everything and going for more. Here are a few book sources if you don't trust the internet:
Aaron Kaplan and * Leonora Reinhold. CO2 CONCENTRATING MECHANISMS IN PHOTOSYNTHETIC MICROORGANISMS. Annual Review of Plant Physiology and Plant Molecular Biology Vol. 50: 539-570 (Volume publication date June 1999).

Badger, Palmqvist, Yu. Measurement of CO2 and HCO3− fluxes in cyanobacteria and microalgae during steady-state photosynthesis. Physiologia Plantarum 90; 3 pp 529-36.

There are literally thousands upon thousands of these available. Most of these you can find the free abstract, whereas others you'd have to subscribe to get the peer-reviewed scientific journals. In any case, those are about as official as you get.

Wow,prove it.Any random person can type they have a degree in anything here,lol.My brother is the one with the PHD,not me.Anyway,it is nice to know people here can't admit when they are wrong.

And I find it funny that you ignore all the evidence in the world for your own naive assumptions. If you insist on being ignorant, then be my guest. No offense, but if your brother is a Ph.D. and he gave you this information, his field isn't microbiology (or maybe not even biology with something this basic). Not one biologist familiar with cyanobacteria will tell you they are non-photosynthetic. That is just plain bad science or ignorance. Have a nice day :D.
 
Lets agree to disagree and move on. The OP can come to their own course of action.

Taking things personal will not benefit anyone.

Thanks.
 
One of the best ways to get rid of it is by simply reducing DOC in the water. Increase skimming and O2 levels in tank. A higher redox is needed. Careful addition of H2O2 or KMnO4(Potassium Permanganate) will help achieve this. I'm am not sure, however, how much is 'too much' when concerning the safety of corals or clams.
