 · We used them in the stores as spot cleaners or on tanks that had ick present as the DE was supposed to filter out things smaller than ick from the water. It's not a 24/7 filter. IMO, it's a better filter than a canister or HOB filter because it filters out smaller particles but, since it's not a full time use filter, it's not my #1 go to filter.

 · When diatoms die, their cell walls are left behind and sink to the bottom of bodies of water. Massive accumulations of diatomrich sediments compact and solidify over long periods of time to form rock rich in fossilized diatoms that is mined for use in abrasives and filters. Diatoms belong to the taxonomic phylum Bacillariophyta.

Using a filter media is important because it prevents the cloths used in a filter press from being blinded, which happens when too many particles are collected and oil can no longer pass through. Diatomaceous earth, also known as diatomite and DE, is the naturally occurring fossilized remains of diatoms—singlecelled aquatic algae.

Unlike conventional aquarium filter, diatom utilizes diatomaceous earth to remove unwanted solid particles from the water. It functions something like a bleaching earth with tiny pores measuring less than 5 micron to absorb and ion exchange with charged contaminant, and therefore the result that you can see is that the water will become crystal clear in just a matter of hours.
