This specific term references a filtration medium widely employed in swimming pool maintenance, available for purchase at a major home improvement retailer. The substance is composed of the fossilized remains of diatoms, a type of hard-shelled algae. This material, in its intended application, traps particulate matter, clarifying water. For instance, a homeowner might search for this substance at a particular chain to maintain the cleanliness of their pool water.
Utilizing this filtration aid offers several advantages. Its porous structure allows for the capture of very fine debris, resulting in exceptionally clear water. Historically, this material has been recognized for its filtration capabilities and has been used in various industries beyond pool maintenance. Its natural origin makes it a generally accepted option for water purification.
