How do I ......

Get rid of Cyno????

I know it has something to do with nutrients in the tank and how I am feeding. Will Macros and a refuge help this out????

Macro in the fuge will help by competing for food. But it's a long shot.

If you want to kill it as soon as possible, you should really cut down food supply, reduce lighting, increase current and make sure your nutrient level, NO3, PO4 are almost undetectable.

Siphoning them out at the same time as water change also act as nutrient export. Instead of them dying in your tank, which re-releases nutrient back into the water, by siphoning them out entirely, you removed them with nutrients locked in their tissues.

I used to have a small bare bottom tank (eclipse 6) that I purposely encourage cyno to grow. The flow rate is slow, with strong lighting 24 hours. I allow cynobacteria to cover all surfaces of the tank, and siphone them all out to achieve nutrient export. The trick is to keep the tank outlet clean so the fragments of the cyno does not flow back into the system.

Are you using a RO/DI unit to purify your water or are you using tap water?

In the begining I was using tap to do everything - top off, fill, everything. Since I have learned of Scripps Pier I have been using that for water changes and since the temp here has gone down I hardly ever use tap at all (maybe 1 every three weeks). I know its bad but dont really wanna go to Aquatic wharehouse to get RO water. Before I started using Scripps pier water I never had a cyno problem though

Supa,

Hippo offers good advice, and I agree that RO/DI would help too. If your problems persist, you might try running a high quality activated carbon for a couple of days each month. Also, do you skim? A skimmer might remove nutrients quicker than macro.

How long has your tank been set up? Cyano is usually a phase. I didn't believe this until one day thick blanket of cyano covering my sand bed and rocks just went away and was replaced by greener algaes, like hair algae...happened almost over night. I did nothing to stop the cyano, except once in a while syphoning what amounted to 10% of it out. Now it's almost completely gone.

Decreasing nutrients helps.

As for light, I think that cyano likes light, but dimer light. So if you increase bright lights it is more quickly replaced by green algae. If you have dim lighting, like regular flourescents, you might want to cut back your lighting. The only difference between the time I had a problem and it going away was that I replaced one of my PCs; I think the "phase" was ending and the brighter light just killed it off. In fact, the only cyano that is left in my tank is in the shade. 8)

I have pc lights and the cyno is still there and growing a bit. Buggin the living hell out of me cause its covers some of my GSP's. Alot of it has been replaced by green hair algea and since I have changed my lights to 8k's I still have the low light algae as well. I do skim Remora witha maxi 1200 hanging on the sump. I think my problem lies within my snad bed. In the begining I didnt put much more than was needed to cover the glass bottom and with my sand sifter goby I dont get all the benefits of a established dsb. There fore in the refuge I am going to have a 5 - 7 in dsb with ultra fine carib sea argonite with plenty macros and a few peices if LR. I think this will help tremendously but it wont happen over night. Any thougths about if this will work or not?

So why not go back to trying tap water again if you never had problems with it? Honestly I think it's your water source.

I too have it, It is not as bad. But it actually started when I did my Fuge. I think it just might be a phase, and will go away. I hope!!! But I have been getting that other Cyno that has Bubbles. It traps the Oxygen I don't know really need to read a bit more on it. Well I hope you can get rid of yours. I am actually almost rid of it.

I have that too in places on the back glass that I don't clean that often. I don't think it's trapping oxygen though; I think it produces those bubbles. They form very slowly in my tank...if I clean the area once a week, I don't see them.

All I know is that I always had nutrient problems before algae started growing on the rocks and glass. Now my nitrates are zero all the time. I'll gladly suffer some unsightly algae as long as my water quality stays perfect.

Usually the cyno starts then is covered in green algae and things like that. I dont know I am getting so mad at my tank. the only corals that are doing well in the tank are my shrooms everything else )gsp's and xenia) are fading away. I am thinking of just going fo w/LR

The scripps pier water is my problem?? :?:

I thought it would be more of a solution
