Yeah Low'n'Slo is EXACTLY the same as generic Dry Acid, except for, of course, the excessive price charged for it.

Total Alkalinity Raiser (and I think it's Biogard's Balance Pack 300) is nothing more than Arm&Hammer baking soda.

pH Up!, (and I think it's Biogard's Balance Pack 200) and Soda Ash are nothing more than Arm&Hammer Washing Soda (in the yellow box)

6% Liquid Shock is 6% Laundry bleach.

It's deceptive sales practices like this that get all of us to doubt pool chem companies' guidance.
