I know you guys aren't into systems like this but I respect your opinions as you're all very knowledgeable.
Anyway, I have as an experiment I turned off the spray bar that causes the tank water to rotate in a counter clockwise manner to create a centripetal self cleaning action that moves settleable solids to the center drain. Turns out turning it off had no effect on the swimming rate. Next I turned it back on and turned off the center diffuser. Many of the fish stopped swimming and just hung in the water column. Not sure if it was just concern or curiosity that something had suddenly changed, but many did stop swimming around and around. I plan on turning it off for an extended period of time and monitoring the D.O. to see if this is indeed it.
Do you guys think that the turbulence by the diffuser is the or a synergistic effect along with the spray bar, or do you have any other ideas? Have you ever heard of this?
I'm considering moving them into a larger tank that shares the biofilter where there are bluegills. Then using this tank as a centralized tank that I can boil the piss out with a diffuser and potentially turn off the diffuser in the tank that has the fish or turn it down to low rate. I could also insert a foam fractionator into this then fishless tank with no issues with fish.
