I don't know what is going on! I am cycling my tank right now with shrimp. I have been monitoring ammonia, nitrite, and nitrate about every other day. Everything was going great....my ammonia peaked out at 0.5 and fell to zero, my nitrites were on the rise, and soon after, my nitrates started to rise. Then something very weird happened.
At three weeks into it my nitrites stabilized between 2.0 - 2.5 and now my nitrates have started to fall from 20 down to almost zero. I thought that as the tank matured the nitrites would slowly fall and the nitrates would start to rise. What is the deal??!! I have a 200 gal
tank with two T4 velocity pumps, a wet/dry, and biobale in my overflows. One of the pumps is a separate pump just for particulate filtration. Do I just have a bad test kit? Am I doing or thinking something incorrectly? Please help.
