I use 31.45% MA to keep my pH between 7.5 & 7.8. I find that I have to add approx. 14oz. or so every other day to maintain these levels. I also have a little high CH (350-400) so I really try to keep my pH at the lower levels.
I added Borates about 6 weeks ago and the water feels & looks great but it has NOT reduced my MA usage one bit. With Borates or without Borates my MA is the same.
My question is, it seems to me I sure use a lot of MA. I'm like after a while I'm swimming in MA with a little water added....LOL. But seriously, is adding 14oz of MA every other day about normal to maintain these pH levels? I am also running my SWG @ 65% which I know causes some aeration which raises my pH some too and may be contributing to me having to add more MA during the summer.
Also, I was wondering what happens to all this MA. Does it evaporate with the water or does it keep accumulating in the pool?
