Dave,
I assume your skimmer is not working as you like... I have seen mixed results with the "PoolSkim" in the posts I have read here at TFP.
The number one reason for poor skimming is a missing, or nonworking, weir door.
My pump runs at 1250 RPM and my pool skims just fine.. Skimmers do not reach out and suck things in that are in the middle of the pool.
It just takes a little patience and time to let the skimmers work.. The key in my mind is not how fast they work, but is the basket full of stuff from the night before?
Thanks,
Jim R.
