When I first set the tank up I let it run for about two weeks and the pet store told me to add a couple of fish (black skirt tetras). I checked the levels on a constant basis and while it never disappeared the ammonia levels were low. I would do partial water changes every few days and added ammonia detox and ammo chips to my filters. I thought I had the problem solved so I added a dwarf gourami and three albino cory's over the course of about two more weeks. No problems! Two weeks later I added a couple of small silver dollars and the next day they were dead. I checked the water and the ammonia was really high so I changed the water (15 gal.) and added more detox. The fish appear to be ok but I can't get rid of the ammonia. Now I'm thinking that my filter's not good enough so I'm thinking about getting a Magnum 350 with the bio wheel. What do you think.
