Greetings from the west coast of Canada.
I have recently redigned our old filter, tired of retrieving the Laguna Powerflowmax from our small 200 gallon pool for cleaning, I have used the same materials as media. The water enters and flows through the media then down and under and back up to the outlet. The flow rate is about 200 gph. Now its time for you folks to be honest and critique, please. We have lots of plants and at last count 3 - 4" Koi, there may be a couple more that have not come out of hibernation yet, water temp is only 47 degrees. The sponges really collected the crud when the old filter was in the pond.
