I'm a new pool owner with a 2 month old pool and trying to get the water balance set. From reading a LOT on this great forum, I'd like to add borates but I haven't yet been able to get the TA level down to the recommended levels on most of the older posts. Does the TA really need to be in recommended 70-80 range before adding the borax/MA? I've been trying the add MA and aerating (6+ gallons of MA so far) but can't seem to get below a TA of about 120 yet. The high TA of my source water really hits the levels when I have to add water (like after a backwash).
My current readings with a Taylor K-2006 and Spinstir -
water temp - 60 F
My source water (tap) has a PH of 8.4, TA of 325, CH of 25.
