Thx for the reply.

My brother in law was concerned because of the high pressure and bubbles coming out into the pool. I believe the bubbles are largely due to the skimmer attachment bringing air into the pump.

All I know is I never want to pay $15 for one of the crappy paper filters that work for 2 days and are never truely cleaned for re-use.

Just having to check the ph and CL is enough fun, never mind a clogged filter every weekend without the capability of vaccuming...

I know, you get what you pay for...
