I have a 10 gal
tank that has been set up for a little over 2 months. I have been doing weekly water changes, haven't added any new fish for a while, and only feed once a day, yet my ammonia is still high. I tested my water today and he is what I got: Ammonia 4.0 ppm
, Nitrites .25 ppm
, Nitrates 20 ppm
. Anyone have any idea why my Ammonia and Nitrites are still up?
