DE in sand filter

[chuck9997]

OK.. HOME DEPOT had D.E... but it was $20.. same thing at WAL-MART.

The D.E. I found was called: D.E. Filter Aid, Pure diatomaceous earth. The box says: Recharges D.E. filters, Improves filtering efficiencies. It was by AQUA CHEM and was $20 for a 24 pound package. I didn't buy it.

Is this what everyone is buying?.. I would like to find the $8.95 bag someone mentioned.

That's exactly what I bought. It will last forever!
Add it slow, watch your filter dP and let it work. There's plenty of posts on this site to tell you how to add it.
I add it slowly until my filter pressure increases by 2 psig. It takes about 24 ounces, or about 2 plastic solo drinking cups worth, in my sand filter.
If your pool is cloudy, it will help clean it up in a hurry.
When you backwash, it will get pushed out of your filter and you will have to re-add. Even still, the 24 pound box will last a lifetime.

Thats the exact stuff I got, it just happened to be on sale at KMart. I guess I lucked out!

Ok.. I found the D.E. at K-Mart.. The 24 pound bag was $15.29.. not bad.

Thanks for everyone's help.
