    "A 1 lb. coffee can only holds ~ ½ lb. DE"

    Hi- what about the modern plastic coffee cans that hold 33.9 oz. of coffee? I'm thinking they measure about .102 cu. ft. but am having trouble getting an answer on the actual wt/cu ft of the DE filter media. Does 14 lb/cu ft sound right? that would make the plastic jugs hold 1.43 lb. of DE.

    By the way the hill beside my pool did not slide and collapse my pool wall, even with the wettest winter an spring in a long long time.

    ...(your treatise on DE filters is terrif.)

    OK, figured it out, if a 1 lb coffee can 4" dia x 5.5" long holds 1/2 lb, how much does the bigger 33 oz plastic jug hold? the math was simple, works out to 1.1 lb or something. Silly me, never mind. Thanks all.

    By the way, our first pool had a DE filter and it worked great except for once when a cracked manifold was letting DE into the pool, so DE is all I have ever known. I bought a new Hayward 48 sf Progrid last year and love it. Backwashing is much simplified

    ah, yes, a little scientific weigh-in using the ultra precise UPS package scale endorses my hazy calculations, figure 1.06 - 1.1 pounds DE to fill the large, modern, plastic coffee container.
