ok, so i have done a water change and tested water....
ph7.4, amm 0, nitrate 5ppm, nitrite.25( they are usually @ 0 ) what could have brought this up??
I also added a AC110 last week to give it more filtration. so i have an eheim 2028 and a AC110. I think that this is definately enough filtration for the tank. what could be the reason for the spike in nitrites??
