Well I think that stress zyme bacteria worked! Added some more Ammonia yesterday, took it back up to about 3-5 ppm, still no nitrites and 5 ppm nitrates. Today ammonia is down again to 1 ppm, nitrites are still 0 and nitrates are 10ppm...I think this may be working. I shouldn't put any more ammonia in if it hits zero right? Or should I until I put fish in it?
