I have a Pentair DE filter, 80 SQ ft.and Variable pump, Pentair VS 3050, 22000 gal pool, inground.
After backwashing the DE filter, how much DE media should I add back ?
It seems that the pressure on the filter gauge varies with the speed of the pump, so which speed would accurately reflect the true pressure of the filter ?
Thanks
