50 ppm Borax

[CAP]

Test strips have been ordered.....thanks for the link. Now I'll just wait for the strips to come in and arm myself with some muratic acid and hit wal-mart for some borax.

According to the bleach calculator for borax I would need to add about 20 lbs of borax to my 20,000 gallon pool to achieve close to 50 ppm borax? Am I figuring that right? That sounds like an awful lot of borax. Just want to make sure I'm figuring that right. Obviously I wouldn't add all of that borax at once but add it over several days, and adjust the PH back down with acid.

Does this sound about right? What is Ben's take on this borax method?

Thanks again for the help.

Cap,
The BioGuard "Alex" printout from the pool store shows Borate level also (as Optimizer +). Here is the MSDS for Optimizer.

Each box is 4#, so 5 boxes sounds about right.
