Cyano, help me rid the tank of it please

Tmoriarty · 02/02/2012, 04:15 PM

So over the last 3 weeks or so I have had an outbreak of cyano. Its a pretty decent outbreak. First I will list levels in the tank.

No3-15
No2- 0
Amm- 0
Calc- 400
Po4- 0
SG- 35ppt
temp- 80

The cyano has been driving me nuts, tank is about 6 months old. All growth is excellent, some of my sps has grown almost an inch in the last 3 months. Everything seems to be happy.... minus the annoying cyano.

I am going to try lights out for 2/3 days but it will just put the nutrients back into the water column, which in turn will probably re-create more cyano. I started running GFO 2 weeks ago and it hasn't seemed to help. I changed it out after a week just to make sure it wasn't exauhsted.

What else can I do to get this under control and keep it out of my tank. Tank is the 203g in my sig, lights are 750w 20k mh, 8hours a day. Refugium underneath is on 8hours a day off my tank lights and I have chaeto in the refugium section.

I have dropped my feeding, but I do not really overfeed anyways. I have a decent number of fish, but they are pretty small in general (12 fish, 3 are 1inch chromies)

Sorry I am all over the place, just trying to answer as many of the impending questions before they come. If anything else is needed let me know. Thanks for any help.

from what i have been told you can pull large clumps out. manually remove as much a you can then lights out and no feeding...not even moon lights . then run for a week and repeat

i lost my last tank to it act fast.

How old are your lights? How often are you doing water changes? When you do water changes are you trying to syphon as much out? Is there any ambient light able to access your tank?

These were things that affected my tank. I just dilligently did water changes to keep it under control

Skim heavy, do lots of water changes, manually remove, and change gfo frequently. FYI the cyano probably helped grow your sps (no cyano = more phosphate in the water

)

Ive been changing my cyano, did 2 days lights out and it helped... but it came back. Im planning on doing another 2 days next week. Lights are 6 months old MH's. There is no ambient light entering the tank. I do weekly water changes of 10%... sometimes i wait two weeks and do 15% (of tank volume not actual, actual is probably closer to 20% a week). I do syphon what i can when i do my water changes but with a 30" tank its a bit of a hassle to get to it all. Did a 20% water change (40 gallons) the day after the lights out.

Any other solutions? what is the spectrum of light that grows cyano the best, maybe i can try a diffrent spectrum of bulbs and hinder the cyano there.

If the system was running fine and now you have the cyano outbreak I would continue to perform the regular maintinance along with a bit bigger water changes. Also, try Chimipure Elite for carbon if not already using. I had a cyano outbreak with GFO running. Changing the GFO did not do anything. Once I put the ChemiPure in the tank the cyano went away.

Good luck!!
