Bacterial bloom

[SnowboardHull]

Hey guys. I currently have a tank which looks like its full of milk! My ammonia level is .25ppm but my nitrites and nitrates are through the roof. Im doing PWCs as often as I can but the levels dont seem to be falling. Any ideas on what I can do to help the situation?

Well, maybe try lowering the amount of ammonia you supply, and lowering a bit the water changes? Usually, bacterial bloom is when the bb is disturbed. Also, you might be supplying too much ammonia?

Does the tank have fish? If so what kind and how many? What size tank? What test kit are you using? How long has it been set up? What are the exact readings for nitrate and nitrite according to the test? What dechlorinator are you using?

How much water are you changing? If nitrates/nitrites are that high doing small water changes won't move the levels much. Try doing larger water changes (50%) a few hours apart. Also test your tap water for nitrite and nitrate to see if any are coming from there.

The tank has about 10 guppies, 6 neons, 2 ottos and a pleco. Tank has been setup for a few months now! Its a 20Gal long. Using API master kit for water testing, stress zyme for chlorine. Dont have the kit in front of me at the moment but the readings were as high as the chart allows?
