Got a question for you guys/gals. Have a 72" Loop marine bundle on the tank, which I absolutely love the lighting on. For some strange reason the return pump in the sump has a mind of its own and will speed up and slow down at will. We have it programmed for 30% but still speeding up at different times of the day. Anyone else have this setup have this issue?
Also would like some input on what might have occurred in my tank. Before all of the fish started dying hubby had added a carbon filter to the side of the return end of the sump. All of the rock in the tank had a black film to them and we figured out the carbon filter was grinding up the carbon and it was getting in the DT. Could this have caused any of the issues with the fish and not a disease like I first thought. Still have the 3 fish that survived in a QT for now. We have since removed the carbon filter. Skimmer was still getting some of the carbon out of the tank last week but not seeing anything right now.
