Or get a protein skimmer and make sure you have good surface agitation to break up the fil and push it back into the water column so the filter and skimmer can pick it up. I had to make a decision between hob device and running it back in through the filter, but the skimmer gave me more bang for the buck at removing more junk and not loading up a filter...Try a coralife super skimmer...good bang for the buck
