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 DE...it 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?
