I could move the biofiliters to one tank or the other and still have them if I need them.

The real issue is that if there is no biofiltration I'd have to do serious daily water changes to keep ammonia levels low enough to avoid stressing already stressed/sick fish.

Gotta keep looking for healthy looking fish is all.....
