probaly the easiest way to check it is to use bleachcalc to get a certain ppm increase and then test with the strips to see if it is in the ballpark.Originally Posted by mwsmith2
Well, I didn't create the formula it uses, that's for sure. It was a huge post on the old forum that outlined the chemistry behind it. There was a discussion about decahydrate vs pentahydrate in there. I wish I would have saved it, but I didn't. I do believe I have the math about here somewhere if I can dig it up.

According to the "Alex" printout, you need to add 1# Sodium Bisulphate for each 2# Borax. 1 Qt. Muriatic acid = 2.5 # Sodium Bisulphate.

This seems like a good idea to raise the borate level to the 50 ppm level and creating an algistatic state. I found a patent from 1986 claiming borates are also algicidal: http://www.freepatentsonline.com/4594091.pdf
(does such reading belong in "The China Shop"?)
One last thing 20 mule team borax comes in 76 oz. boxes, coming to 4.75 lbs., so if you overshoot the dose is there any harm in putting in too many borates?
According to Proteam's literature on Supreme you need 3/4 lb (12 oz by weight) of sodium bisulfate or 10 oz by volume of muriatic acid for each pound of Supreme (Sodium Tetraborate Pentahydrate)Originally Posted by Henry3
