Come spring start up, I realized my old filter was completely shot: uv light shattered, canister split, unfixable. I replaced it with a new pressure/biological filter, but of course that means my system needs to completely cycle all over again. I have 3 air pumps going and the pressure filter is running, so I have plenty of circulation. Recently, some ammonia started registering on the test results. I've stopped feeding the fish and I've done two 50% water changes over the past 2 days. I've also been adding in beneficial bacteria to help start up the system. My biggest koi, about 19 inches, flashes occasionally. She's not rubbing against the floor or sides. She just swims through the air pump and flashes. In addition, the poor things all really want food. Any advice? I'm thinking maybe I should move the two biggest fish into my 300 gallon quarantine tank until the pond finishes cycling.
