I have a 92 gallon corner tank for my oscar, with a diy wet-dry filter system. I need a pump for the return, I was wondering what the recomended gph rating would be for a tank this size. The pump will have to move water approx 4-6 feet to get it from the filter back to the tank. I was also looking at doing a ugj system with 3 or 4 jets. What size pump or power head would be good for this. Thanks for the help.
