Well they've finally got my pool up and running but it's green and full of sand. Of course I want to begin the SLAM process but the pool has lots and lots of sand in the bottom of it due to back fill and grading, etc. (they haven't poured concrete yet).
I have a cartridge filter and I'm not sure I want to just vacuum the sand into the filter, I'm thinking bad things can happen. I have read about "vacuuming to waste" but can't seem to wrap my mind around how to do that with a cartridge filter.
