    Low Flow after Pebble Tec

    Recently had the pool refinished (PebbleTec) and after refill the flows are sluggish. Pressure washed the filter, no change. I am wondering if there is a bunch of debris from the resurfacing in the return or outflow to pool. anyone ever heard of this?

    Do you have a main drain?

    What is your filter pressure normally, and what is it now? That will help narrow down the problem.

    Also, if you can post a full set of chemistry readings, that would help us diagnose the problem.
