I just got my Amazon shipment of Borax today...and also have my MA ready - both amounts according to PoolMath.
I just tested my water and here are my numbers:
water temp 69
FC 7 (I think this is a little high - still trying to "dial in" the SWG
CYA 40 (I hate this test. Seriously. I *think* I finally have the hang of it after several months!)
I've used Borax in our Spa at 40ppm and I love it. It makes such a huge difference in being able to keep the pH stable.
So my question for the pool - based on the above numbers, do you think I'm ready to begin?
