fighting mustard algae

[Kateyru]

At 12:30 pm, FC = 37 so I added 2 more jugs (182oz. each) of bleach then measured pH. I added 50 oz. of acid last night based on pH of 8 BEFORE I started mustard algae shock. The pH is currently over 8. Do I add more acid?
Thanks.

You need to keep your chlorine high -- I haven't re-read the thread, so I don't know how high -- but you ALSO need to keep your pH in range. Add some acid, until it's below 7.8!

Okay. What about TA which was 48 on 7/31?
Thanks.

TA is related to pH, but not the same: you can have hi TA and low pH, hi TA and hi pH, lo TA and lo pH, and lo TA and hi pH!

You need to lower your pH! Once you do, you need to re-test your TA. If your TA is excessively low, you'll need to add bicarbonate, and THEN probably lower pH some again.

I added muriatic acid when I was at home for lunch. Will re-check pH this afternoon and get it down < 7.8 then test TA. I'm continuing to shock at mustard algae level. Pool water seems to have gotten way out of whack...
thanks much!

Did you sign up for the Pool Log? (I haven't matched email addresses with user names yet -- we'll do that in the next few days, and set up all the forms and spreadsheets.)

If not, you need to do so. (Did you get an email about it?)

[Kateyru]

Is the Log the same as Pool Chart Entry and Results forms or Pool History entry or logsheet? If so, those were set up and have some info. I will update if that's where my info needs to be. I have not received an email about the log.
thanks.
