I posted this at the end of the old thread on borate, but have no response.
Then I noticed the advice to start a new thread and not add to old ones, so...
The pool math calculator shows 495 ox of borax for 30 ppm in a 14,100 gal pool.
This calculates out to 250 ppm or about 130 ppm sodium borate, accounting for the decahydrate.
Can someone explain this apparent discrepancy?
