Here are pics of my pool.
Before starting I measured CYA at 0 and Ph at 8.2 so I need to adjust before slamming.
My question is from the pictures should I vacuum to waste before starting. Or get chemicals situated and then vacuum to waste?
I know I need to skim all the stuff off the top.
What should I try to adjust first? CYA or PH? My thoughts are add PH minus till ph in appropriate range then adjust CYA and then come back and check ph again before starting SLAM process.
