Back from Wal-Mart and I added a new pump and two new air curtains. Aeration appears to be up 3 fold.
I turned off the Well water for now as I was worried about possible rust/gases that maybe causing the problem. I am using a water filter that is supposed to cut rust down, but I am not sure that it is enough. Tomorrow I might put something together to run the water through.
Bad news...Lost 6 more RT. The Smaller ones are hurting right now the bigger guys are cruising at the bottom. Hopefully the aeration will save the rest.
