    DE stands for diatomaceous earth. It can be purchased at a pool supply store and at some big box hardware stores like Lowe's or Home Depot. Be sure to get the kind made for pools and not for gardening.

    Here's how you add it to a sand filter...

    From what I can tell, it's not done all that frequently. Then I would have to see a poll for some true numbers. Typically, we see people do it here when they are trying to clear a cloudy pool with a sand filter and for whatever reason, it just seems to be taking longer than desired. Some report that it works quite well and others have reported that they have seen only a negligible difference.

    It can help clear cloudy water a little faster. Don't worry about it if you have clear water.
