My spa tests 30 ppm for borate and my pool tests 50 ppm. Both pool and spa run around pH= 7.3, CYA=30, FC=3-5, and CC always under 0.5 ppm. I run my CA and TA lower in the spa than my Gunite IG pool too--at CA=150 and TA=50. Years ago I owned and maintained a spa and never used Borax. With this spa, whenever I turn on the aeration, my eyes sting and it sometimes even makes me cough. I never have trouble in the pool, but then it doesn't produce an atmosphere of tiny chemical infused bubbles that pop at the surface of the water and deliver a dose of something stingy to my eyes either.
Given that this never happened to me in the past, I'm thinking about dumping the water and re-balancing the new water without Borax!
Any similar experiences here?
