Question:

Water is a filter aid?


Answer:

Filter aid is a generic term for a product that, when poured into your skimmer, will coat the top of the sand in your filter, allowing the filter to catch those tiny bits of dead algae that are currently passing right through and causing the cloudiness. You can use diatomaceous earth, alum or whatever your local pool store recommends as a filter aid. Start with a small amount (about 1/2 cup) and then add only enough additional to raise your pump pressure about 1 pound above the present reading on the gauge.
