Have a 10 gal, IM nano fusion reef...had trouble with keeping water clean and excess nutrients...finally I bought an IM filter sock that fits right in the space where the filter stack used to be...the cheap thing was breaking anyhow...so I put a carbon pillow and phosphate sponge right inside the sock...in a day, my water looks crystal clear...started the tank in June...finally looks great....
