Hello, I am just wondering if it would be good or not to just use my 2 powerhead units and stop with the HOB filter. The reason I ask is my fiancee hates the sound of the water running all the time from it. I at the moment have 2 Penguin 660R's with my UGF and a Aqua-Tech 10-20g HOB. I was thinking about just running one of the power heads reversed and the other normal. I know I would then need to plug one of the holes on the UGF. Would something like this work? Would the RUGF still work as good or not considering it would only be using 1 powerhead? Also would the other powerhead be able to filter like the HOB does. I bought the 660R's with the large prefilter sponges if that matter. Thanks
