Probably a noob question, but I am confused as to what the correct measurement of DE is for my particular filter. I have a Pentair ST50 filter, which is approx. 48 square feet. The filter guide says a 1 pound coffee can covers approximately 5 square feet of filter area, so I am looking at 9-10 scoops for my filter.
I bought a 1 pound DE Scoop off of Amazon... http://www.amazon.com/Blue-Devil-B83...ct_top?ie=UTF8
However this 1 pound scoop says one scoop = 5 square feet of filter area (just like the coffee can). If that is true then I just paid 10 bucks for a slightly prettier coffee can lol. You would think that a 1 pound DE scoop would actually give you 1 pound of DE. Very confusing!
