Hey guys, I posted last week about my tank testing for ammonia. My level reads right at 8.0! It has been there for about a week and a half that I know of. I have changed the water many times, 1/3, 1/2, etc. I have added Seachem Prime and stability. I have added another filter. I have lost about 6 fish total so far. Everyone in the tank now seems ok. They swim around, quite fast, lol. They eat, although I have put them on a diet. I thought maybe the ammonia was coming from over feeding. Now I just don't know what to do? Do I maybe have too many fish? I heard 1" of fish per gallon, but also read that wasn't necessarily true. I most likely do have a few too many, they're addictive. I have 24 total in the tank, not counting my lone ghost shrimp. I have 3 gourami, 1 dwarf gourami, 4 danios, 4 black non tetras, 2 mollys, 3 cherry barbs, 3 red minor tetras, 2 cory cats, 2 platys. I don't think I forgot anybody, lol. My tank is a 55g, I am running a Tetra Whisper 30-60, and a Fluval 50. I don't have any live plants yet, but will they help at this point, will more shrimp or invertebrates help/hurt? I don't have a sick tank to move them to either Suggestions?
