I posted another thread earlier today, but need some advise on what to do with the water in my tank. We are new owners and have two goldfish that were just upgraded to a 20 gallon tank (yes, I know they will need bigger). The tank could not be cycled prior to the fish going in (previous tank had super high ammonia). Current tank had fish in last night around 7 p.m. Prime was used. About 7 a.m. I added Tetra SafeStart, however, Ammonia is now reading between .25 and .75 still (zero nitrate/nitrites; pH 7.6). This afternoon/evening, I have one fish with clamped fins and he either sits up by the filter or down at the bottom (moved up when I turned the tank lights off). From what I have read, I am assuming this may be due to either the high ammonia or just being in a new tank (he was fine last night). Given that I have added SafeStart this morning, could I add some more prime to lock the ammonia, or will that stall the whole process of cycling? Do I need to do anything to lower the pH? Thanks so much!
