I want to add borates to my pool tonight but not one of the 8 pool stores around here carry Borate Test Strips. One place said they can test them there with their machine. I figure I can try to put them at 40ppm-45ppm. And bring in a sample to them maybe Friday. My TA is at 80 and pH 7.4 right now. So I guess my question is, are Borates normally at "0"? Thanks
