I'm about to take the plunge. For my pool (25k) I will need 21 boxes of Borax and 6 gallons of MA. Thus, 3.5 boxes of Borax to 1 gallon of MA. I'm nervous about putting that much MA straight into the pool. I have a large plastic tub that could hold 1/2 keg of beer and ice. I was thinking of putting the tub at the edge of the pool. Fill tub up a bit (about 20 gallons) with water....then add 3.5 boxes of Borax....mix to dissolve....and then a gallon of MA. Mix so the PH of the solution is liner friendly and then dump the solution into the deep end of the pool. Will this work? Or will I asphyxiate (or otherwise) myself when I combine the borax and MA in that small amount of water?
