Thanks, Zardra.
I've got bad news. Yesterday I was dosing heavy for co2 (2 plus bubbles per second), was going to do this just for a few hours. However, I ended up having to work late and fell asleep. I left the co2 on all night. I came into my office this morning and all of my fish were showing signs of oxygen depravation. I immediatly did a 25% water change. I now have my water level low for the return to create as much surface aggitation as possible to help release the co2. After a while I may do another 25% change. Lights are still out, but the fish are looking better. The black veil angel still isn't looking too hot though - I really hope he pulls through.
