I have a Whisper power filter hook up to run my GFO through. The filter is rated at 105 gph and I got it set to about 50 gph. The only thing I can see that a reactor does is run a column of water through the GFO. Where a lot of water get bypass in the power filter. In the same token not all the water volume get through the reactor as well. Does it really make any difference which one you use? If it does let me know.
