Just started keeping fish about two weeks ago and I did some things that I later learned were not the greatest, but I'm learning! I have a TopFin 29 gal starter kit with some pygmy corys, a feed goldfish and I'm planning on adding some cherry barbs which are in quarantine right now. I have had the tank set up for two weeks now and I test the water everyday. I read some ammonia in the first week and did water changes when I read .25 ppm for two days in a row. My current readings use an API Master Test Kit are Ammonia = 0 Nitrite = 0 and Nitrate = 0 Any thoughts?
