DE question

Mar 31, 2007
Frederick, Md.
Please help me with a few questions.

I am new to DE filters.

The pool builder gave me "splash" brand DE. This was white.

I was in Home Depot and saw was tan.

What should I buy??? Tan, white, Home Depot, pool store or mail order?

Is mail order usually the cheapest way to go?

Also, approx. how many cups are in 1 lb. of DE?
