Just wanted to follow up with what happened after my uncle took his fish home. After all that, he threw all his fish in a variety of tanks at his home. He bought a bucket and water pump, and thought that running the tank water through a sponge would remove the ammonia. Wowwww. I explained water changes and tank cycled to him, told him that the red sores on all his fish were ammonia burns. “No ammonias fine. The water parameters are all fine.” He doesn’t listen to anything. Alllll the trouble and allll the loss… he threw all his koi out in a massive index pool with no filtration, no aeration, and very little circulation. Oh and he didn’t dechlorinate. “The chlorine will gas off”. It if it’s chloramine! Then he dumped an algae side in and it killed all his fish. I just try not to think about it anymore, but wanted y’all to hear the end of what happened. Ridiculous, all of it was absolutely pointless. My uncles not an awful person, you know. He just thinks he knows. He thinks he’s doing it right, and doesn’t want to hear it. Ahh. But the pond is doing well, all the plants are coming back and my fish seem to be thriving now.
