[QUOTE=stevehull;40079]After looking at this, you might want to reverse the trapping layers. The last filter element might be the DE, then the sand, then the pea gravel.

Too late for that. There's 40 cm (51 bags at 0.44 cu ft ea.) of 10-20 sand in there already. I'm trying to find 40-70 sand for the remaining ~ 3/4 meter.
