It uses a unique diatom powder to filter particles as small as one diatom in size. Even some parasites and bacteria are large enough to be trapped and pulled out of the water by a diatom filter.
Used properly, your Diatom filter will eliminate the need to "tear down" your aquarium to clean.
Model D-1 is for most routine cleaning jobs. Filters over 250 GPH. Clears a 10 gallon tank micron free in 12 minutes.
