My 1 lb DE scoop doesn't really hold an lb!

[waste]

Rockker and all, there are scoops that hold 1 lb of de, there are also scoops that hold 3/4 lb (and as far as I know 1/2lb). It's close enough to the end of the season not to have to worry about it, unless you're having major filter problems. When you close your pool, take the filter apart and thoroughly wash the grids or fingers, this will take care of any 'under' or 'over' charging of the filter, but it's a good idea to know what your scoop adds for next year. Give me a few minutes and I'll link some of my past advice on 'backwashing' a DE filter.

Heres a thred that contains most of my advice on DE filters (if you have a 'bump' filter, read the entire thread) https://poolforum.com/pf2/showthread.php?t=3613
