Does Alkalinity ever drop on its own do to sunlight or bleach or anything else we put in the pool? With a high TA from our water it seems the best way to lower Ph when need be is to add acid and aerate right? Am I missing something?
waterbear said:This is exactly why it's a good idea not to buy anything other than bleach until you test your water and fill water (and also why I have objected and still object to the name BBB since it really does not bear any reality to what is needed in the pool unless the primary sanitizer is trichlor and the bleach is just used to shock.) If you want a three letter acronym then ABC is more accurate for Acid, Bleach, and CYA. IF you buy these things you will use them all sooner or later!
