Aquarium Diatom Filters
Aquarium diatom filters are unsurpassed in filtration power and polish your water to perfect clarity using diatomaceous earth - an organic sediment with a unique pore structure that will trap the smallest debris (as small as 1 micron). Aquarium diatom filters promote faster fish healing by removing organics and parasites. Because they are so thorough, diatom filters need frequent cleaning. We recommend using them regularly instead of running them continuously, or when you need to tackle a tough particulate problem, stubborn algae, or to polish up your water.
