Hello TFF. I've been using sponge filters in my fish tanks for quite a few years and found the course filters work the best. MaxxClean has a very good one. The courser filter is easier to clean, doesn't clog between cleanings and supplies good water movement that keeps oxygen mixed into the water. This type of filter won't trap fry or small fish like some of the HOBs can. I change half the water in my tanks every week and always squeeze out the filters. If you follow an aggressive water change routine, you won't need high end filtration equipment, because the filter will just be moving water that's already clean. You'll need an air pump to run the sponge and AquaMiracle has one of the best I've used.
