I have a Whisperflo 2 two speed pump (1.5/.5 HP). I typically backwash on low speed, but I'm not sure if I can use high speed. It seems like high speed would do a much better job dislodging the sludge, but I'm afraid it could damage the grids.
Can anyone tell me if it's okay to backwash my DE filter on high or if I need to keep it on low?
Thanks!
