I was first introduced to BBB at PS websight a few years ago. I do not understand the resoning for the Borax to raise PH and Baking soda to raise Alk as opposed to soda ash for PH and bicarbonate of soda for alk.
Can someone shed a little light on the pros and cons. I have always bought Soda ash and Bicarb in 50lb bags to get the best deals. I am in amazement at what I see in the pool store for what they get for the same stuff in fancy little plastic bottles with big brand names on the label. Proves there is a sucker born every now and again.
