So here are my current pool water readings:
CH: 750 (a pool store read 750, while I get 450 with my Taylor 2006 kit??)
My pool was resurfaced (pebble) exactly 1 year ago and filled. It has only been "shocked" once when the pool was first filled by a pool service. The pool service was using trichlor pucks during this time, which explains the high CYA. I live in Phoenix, so I'm guessing the high CH is from all the water evaporation that takes place in the summer, since the CH of the fill water is much lower (150 I believe). Just wanted to see if the CYA and CH readings seem "reasonable" for 1-year old pool water in Phoenix(?).
Secondly, I wanted to verify the recommended action would be to do a partial/full drain of the pool water (based on the CYA and CH levels). I no longer use a pool service, so am trying to decide if fetching/storing bottles of bleach is going to be practical for me (rather than using pucks and draining the water every year).
Any thoughts and/or recommendations are much appreciated.
