So my Pool has become crystal clear, its wonderfull. My only problem right now is Tucson Monsoon rain and Fresh plaster, are casuing PH to rise pretty rapidly. This week I had to add 15oz of MA every day it rained to drop it from 7.8 to 7.5. I am pretty sure this is just the plaster and rain, but I was wondering if adding some Borax to condition the water will help any. I have been thinking about this addition this week, I wanted some opinions on if it will affect fresh plaster or not.
Also, Sunlight is still creating havoc on my FC levels, Im seeing drops of 3-4ppm pr day, <.5 at night. CC still at zero. My current CYA is 40, Suggested range is 30-50 for CYA for my pool, which puts Target FC at 5ish. I was told to keep it around 5 for the plaster so I was thinking this would be a good number to hold. So I'm looking for some advice, if I bump CYA to 50, and target FC will be around 6ish, would this cause any complications for the plaster? I donít think it will, I belive the guy was just a sales man quoting numbers to me.
Anyone else in Southern Arizona care to comment on their CYA levels for our high levels of heat and constant sunlight?
