Swimming Pool Filter media for Diatomaceous Earth Pool Filters.

Diatomite, or diatomaceous earth (DE), has a very small particle size, a high porosity, and crystalline structure, making it an excellent filtration medium. It is an effective, common choice for pool filters, and has been commercially sold as a filter media for over a century. Diatomaceous earth pool filters filter down to an impressive three to five microns. The human eye can only see particles 35 microns, so no wonder this filter aid is said to make your pool "crystal clear. This type of pool filter media option does remove algae, amoebae, bacteria, and other foreign matter that some other filters miss.
