I'm trying to determine the borate level in my spa.
I'm adding the Borax / Acid mix to help with my chemistry and bathing quality.
I got the La Motte test strips, but, as always, they are very hard to read.
(I either have 50 ppm, 80 ppm or significantly more than 80 ppm..!?!)
Does anyone make a drop-test kit for borates?
Thanks - D
