I would like to hear experts' experiences with how to best apply DE to your filter membranes.

1. I have a 2-speed pool pump, with full at 1.5 HP. After I clean my DE filter, I dump the DE through my skimmer. In order to achieve a good even coating on the membranes, is it better to do this while the pump is running on low speed or high speed?

2. Is there any technique whereby before you put on the filter tank cover (a.k.a. upper half part of the tank) you would spray diluted DE at your membrane, again, to achieve a good even coating? Does anybody do that or is that not recommended for whatever reasons?

Thank you for your help.
