Cyanobacterial blooms are usually caused by a rise in nitrogen and/or phosphorous levels. If you can give specific details about your tank (specific species, # of organisms, water test results, water temp, light wattage/duration, any plants, etc.) I can help you. Think of the cyano as a symptom; to treat it for the long term we have to know the underlying cause.

In the mean time, back off on feeding, if you can do so safely, and increase your water changes.

Breeding pair of brevis minutus, 5 white clouds, ammonia 0, nitrites 0, nitrates 0, ph 8.5-9, temp 80*f, light is wtevr comes with the tank, 7am-6pm lighting period, anubis nana and a little dhg 4 plants, 60% water changes once or twice a week. I dont feed that much in the first place, so i cnt cut back. Its been setup for 7 months now, so its not still cycling. Is there anything else u need to know about the tank?

Well, that mostly seems to be within normal paramaters. Do you use tap water for changes? That may be a source of excess phosphates in your tank. Physically remove as much of the cyanobacteria as you can, and try using water purified via reverse osmosis for your next few water changes (often available from water fill stations at local grocery stores). Also, 11 hours of direct light is pretty long. I'd drop it down to 8, at least until your pest problem is completely taken care of. Cyanobacteria use light and inorganic phosphates to produce energy. Limit their access to necessary fuels and they will stop plaguing your tank.

Yes i use tap water, i got a well. Put i use it on all other 4 tanks i got and no issue. Also same light times on all the tanks to. If it is in 1 tank wouldnt it be in at least one more tank???

How old are the bulbs?

The tank has actually been setup for 6 months so, 6 months. But they r leds that come with the tank.

Try other suggestions first, but just FYI, maracyn in your tank will nuke the cyano pretty fast. Just make sure you remove fish. Medicine should be the FINAL resort, right before bleach, but I once had cyano that would never go away no matter what I tried and ever since using maracyn, it has never come back.

Never good to throw a problem at a problem. Go to the source. Overstocking, build up of nutrients,overfeeding,frequency or size of water changes, flow is too slow or dead spots. An imbalance of some kind is what causes cyano.

Thx 4 the idea. I did u big water change yesterday and removed almost all of it. I am going 2 do more water changes and shorten the lighting.
