Okay! So I got a 125 gallon about 2 weeks ago, right after my 55 had basically crashed. Fish were dying, the ammonia tests were basically black, my ray died, fish were getting fungus it was chaos! I moved all my living, non sick fish to the 125 including one established penguin 350 filter. Also on the 125 I have a fluval fx5 with two trays of biomax and carbon in the bottom tray. Also a few live plants. The stock in this tank is 2 angels, 4 platinum tetras, a BGK, 3 clown loaches, a 3 spot gourami, and a gold gourami. Now yes I know this way too much fish for a tank that's supposed to be cycling but I had no choice, they would have surely been dead in the 55. Now here's my dilemma, the ammonia WILL NOT GO DOWN!!! The fish all look very healthy, the clown loaches have their full color and are extremely active, I use them as an example because I know they're sometimes called indicator fish. My theory is that I'm getting false readings because there's just no way its been the same color on the test after so many water changes and very very light feedings (one feeding every 3 days). Now the reason I bring up false readings is because until a few hours ago I had a bag of ammonia remover in the penguin 350 when I had the 55 in a desperate attempt to save it, therefore the ammonia remover was also in the 125. Could that have been providing false readings? Because according to my lfs the established filter should've established this new tank "immediately" what do you guys think? I just want this nightmare to be over
