http://www.thepoolpros.com/borax.html As to calculated, I must be doing something wrong today, I keep coming up with 236 ppm at that rate. Maybe I need to align my calculator...........
The page you reference will only bring the borate to 35 ppm if you follow their directions. FWIW, I am the grandfather of using borate in the water here, at TFP and at PoolSpaForum so you might want to chill a bit. Our info is correct. Yours has not proven to be so based on the corrections that both Ben and I have made to your previous posts.
Sprinling a box or two of borax in the water and letting it sit overnight is not going to do much in the average swimming pool (of 10k to 20k gallons) except perhaps raise the pH a bit. Not quite sure you are posting that bit of info. It's really worthless. 25 ppm is the minimum active borate concentration for algaestatic effect and 30 to 50 ppm for pH buffering effect.
