I've been trying to lower my TA for the past few weeks and can't seem to get it to budge (it's always at 90). I've followed the instructions by adding MA to reduce PH to around 7.0 or 7.2 and then aerate. I'm using my SPA spillerover and a table rock water fall to aerate. Still my TA doesn't seem to reduce at all.
Here are my results today.
I added more MA to reduce my PH to around 7.2. I've also added some more CYA to get it to 70 (will check results later next week).
I would really like to add borates to my pool as well to around 50. But, can't seem to get my TA down. What else can I do?
