DE

[cheshamjim]

What is DE's role in pool maintenance? I understand that there are DE filter systems and that these are very effective at filtering ultra small micron particles from the water. But I've also read that DE is used as an additive (not a filter medium) to the water. It somehow "cleans" water?

Shucks, I've even read that its great against ant colonies and for pets (flea control and food supplement). But that's too far off topic. What does it do for pools?
