I have been trying to lower my TA for a year, since my pool was resurfaced & refilled. Not yet knowing how to startup myself, I paid guys to do it, who put in too much “Alk Up” or whatever it’s called.
I can’t do it. I understand the recommended process, but it doesn’t work. With the constant pH rise from new plaster, I thought lowering TA with MA would be a breeze. Nope. My TA wants to be 120. Sometimes it seems to drift up to 130, and sometimes I can get it down to 110 temporarily.
Now my pH is finally stable. I give up on the TA. My fill water has 40 TA, but I ain’t gonna drain & fill just for that.
