I have been testing my water and all the other test come out good but not the ammonia. How can that be if I may ask that one is so high but the others are low?
Need more info. How long has the tank been running, what size tank, what kind if filtration, what type & how many fish, & what the other test results are. How high is the ammo?
I reckon you just need some 'good' bacteria which will eventually break the ammonia down to nitrite...which will eventually break down to nitrate... Or at least, that's how I understand it
