I plan to drain my pool in the next 24 hours to solve my CYA problem of 280 ppm due to puck drama from previous owners. While the pool is empty for a short period, is there any other preventative maintenance that I should perform?
I am already scheduled for bead blasting my calcium silicate on the waterline tile that I'm told is a result of the volcanic past of our fill water (Hawaii). It was suggested that I acid wash the one inch square tile that makes up the pool, and I've also been advised to consider skim coating the grout. I'll have to read the forums more, as I'm not familiar with how (or when) to do either.
Test results from Taylor K-2006
FC: 12, CC: 0
pH: 7.0 (never seen higher than this, though my previous pool tech always read 7.4)
Ca hardness: 180
CYA: 280 (had to combine 3 parts tap water and one part pool water to estimate)
Thanks in advance for any advice. Posting via Tapatalk so not sure my signature will post - will add if needed.
