I have an undergravel filter in my 75g tank and use 2 402 powerheads. I also have an Aquaclear on the back. Without starting a debate over UGF, I am interested in switching the flow making the filters RUGF. I understand this will increase the filters capacity. Are there any risks in doing this in an established and cycled tank? My fish are growing and all though I currently have no problems, I worry about the increasing bioload.
The tank occupants are 5 Angels, 2 Pearl Gouramis, 3 Clown Loaches, 2 Siamese Algae Eaters, 1 Red Tailed Black Shark and a Bristlenose Pleco.
