Any comments/suggestions welcomed....I want to start using/adding borates to my 21,000+- gal SWG pool with integrated spa/spillover. My current Taylor K2006 and Lamotte Borate test strips show:
FAC - 12.6
TC - 0 - .1
Salt - 2800
CH - 400
CYA - 90
TA - 90
pH - 7.8
Borates - 0-10 maybe? very low. I have not added any during the 3.5 years I have owned the pool.
Not sure why my FAC is so high. Reading Pool School (again and again) to try to understand. Is there anything so off with these readings that would prevent be from adding the Borax and MA right now? Something need adjusting a little prior to doing this?
My math shows that I should add about 15 boxes of Mule Team Borax, the 76 oz ones and about 4 gals of acid. I don't know the exact size of the pool in gallons or sure of the exact Borate reading so my plan is to sneak up on it and test along the way. Start with 12 boxes and 3 gallons of MA, something like that. Anything wrong with what I am doing? Thanks in advance!
