how much muriatic acid

[mwsmith2]

I would strongly recommend against using a formula to calculate anything more than a 0.2 pH drop. That's why the formula is limited like that. Your results could be unpredictable.

Thanks. That's what I have been trying to do. I guess it will just take a while. Is it okay to check ph several times a day and add more acid to keep the ph at 7.0 or should you just do that once a day?

When I have my alkalinity set properly, I am able to hit .4 PH drops right on the money but that does come with experience.

Mark,

I agree, but you have two big BUTs in there:

1. Alk set properly
2. Experience with the pool

That combination can go a long way to hitting a mark. New(ish) folks might not be so lucky!

I am still a little confused. Should I just check PH and Alk once a day and if needed add acid only once a day?

That's what I plan to do.

I think all you'll waste is time.

I found the best time to add acid is at the beginning of your circulation cycle and the best time to measure PH is at the end of your circulation cycle. If you are running 24/7, then measure 12 hours after acid addition.

Okay, I will try that. Thanks for the help.
