It may be useful to put Poret foam under this pre-filter to the water line in the reactor as well, to cut out the noise of running water. The water would drain from the tank through your drain hoses, enter the pre-filter, drain into the fluidized Kaldness bio media, leech through the Poret foam into the pump area of the sump, and be pumped back into the tank. It works great, I have my 240 set up this way, only my sump is an old 55 gal. aquarium. (Note: I eventually removed the pre-filter altogether from my setup, and just let the drains exit under water in the reactor to prevent the water noise. All mechanical filtration is done by the Poret divider. It's just much simpler, and the tank water is just as clear. That 4" thick foam traps everything, and can go a long time between cleanings. Amazing stuff. I clean the sump every few months anyway, so it's no big deal.)
