I'm trying to get my head around the cost benefit of using liquid bleach (sodium hypochlorite) vs triclor. My pool supply warehouse has 15 gallons of 12.5% at $95 compared to 40lbs of triclor at $85. Running the numbers through the calculator indicates there nearly 3x more FC in the triclor. Being a chemist, I'm definitely on board with most everything advocated on BBB; I just can't get past this on point. And to be clear, I'm not trying to be a wise guy. I just want a clear picture of how I'll maintain my pool this summer with opening day being next weekend.
