Ascorbic versus Oxalic Acid / CYA pre-dilution

[duraleigh]

Hi, Paul,

I can't comment on the stain issue...wish I knew more.

Your CYA of 33 (is that a pool store reading?) and Cl of 4-6ppm are just fine. Your CYA will slowly rise if you continue using pucks. You might want to think about an alternate source of Cl.

Once again thank you to both of you.

I will drop the ph to 7.2 and put a puck in the basket. I will also add more metal out and use liquid chlorine to adjust cl in the future.
