I am having nitrite problems and cannot figure out why. I have a 40 gallon tank, and after having problems getting it to cycle correctly, I purchased a package of MarineLand Labs Bio-Spira. i have dosed the tank three times with the bio spira, and the water seemed to be fine for several weeks, but recently the nitrite levels have skyrocketed (over 10 according to my test strips). Since I found this problem, I have been feeding my fish only once a day, and only a small amount, so that there is none left in the water. I have been doing between 10% and 20% water changes every day since the middle of last week, but nothing seems to be helping. The only fish that seems to be ill is a small red tailed shark. My gouramis, tetras, angels, and my pleco all seem normal. Does anyone know anything I could try to fix this problem? It is driving me insain. Since I've installed this tank I've had nothing but problems, and I though I had finally had all the problems worked out, and then this happens. Everything I have read on the internet on the subject of nitrite levels said to change water every day and it will go down in a few days. its been over a week now and the problem seems to have gotten worse. The water is crystal clear, there is no odor, and the gravel appears spotless.
Any information on how to fix this is greatly appreciated.
