The truth is: If you use bleach you aren't buying the pool store guy's expensive chemicals. Pool stores sell bleach ALL THE TIME! They sell Ultra Bleach as "6% Liquid Chlorine" but it's EXACTLY THE SAME as unscented Ultra Bleach--different label.
They are told bleach will damage liners and add "extra stuff" and they pass that on. It's pure BS. They also sell "Total Alkalinity Raiser" for $12 for 4 lbs. At that rate 12 lbs will cost $36. You can buy 12 lbs of Arm&Hammer baking soda at CostCo for $3.50 and THEY ARE BOTH SODIUM BICARBONATE!
I use bleach for chlorine, Baking soda to raise Tot Alk, Borax (yeah, the laundry product) to raise pH. MUCH cheaper!
