I have 3 filters. An XP4, AC110, and a penguin 280. I cleaned the two HOB filters and NOT the canister. I also replaced two large plastic plants that have been in the tank since it's inception, it was loaded with growth (and Iam sure bacteria). Anyway, all the fish look good. The Ammonia is pretty high..I need to lower it fast. I think I lost my parrot last night due to the ammonia levels. I am changing water like crazy..Something I can grab at the LFS?
