I’ve seen it mentioned that I can use BTB dye and mannitol powder to test for borates. How is this used?
 

There is no need for borates on a pool of your type.
 

Hmmm,... after reading this, I thought I had the perfect set up for borates. I’m hoping to extend the life of my SWG, and enjoy the feel of the water. What am I missing?
At any rate, it’s too late , the Borates are in the pool!
 
I put borax in my AGP to raise pH. I only have about 7 ppm borates, but I can feel the difference in the water. It's silky feeling, and when I get out and it dries, my skin feels smooth and soft.
Thank you!! I’m hoping to love the feel and to get longer life from my SWG! My pH hasn’t raised past 7.5 since adding the Borax and MA,.. before it would raise to 7.8-8.2 almost every day.
