I forgot to ad, I did make one mistake, that was not putting the baskets back in the skimmer/pump... sucked some ice "fingers" in while it was running, made some nasty crunching sounds... I scrambled and found the baskets and put them back in ASAP... But, I really hope I didn't do any damage to the impeller.

Pressure didn't seem to be much different, so I am hoping if there is any damage it is minimal... On high the system still shows 12psi of pressure at the filter... It is 11-12psi with clean filters, so I think I am OK. If anything I know the pump I have is a newer model (Pentair Dynamo 1.5hp 2-speed), so I will make a note and when I do a filter cleaning this summer (I cleaned the cartridges just before winterizing) I will see about disassembling the impeller housing and checking it out... I do believe a new impeller isn't very expensive, so if there is any damage I will just replace it...
