PH going up again!

[Mr.Mooks]

Thanks Janet. I am not listening to the pool store just getting my test there. I have only ever added what people here tell me too. I am in Canada and a Taylor kit cost alot here. So as I am new to pools I get the water test done at pool store. What a bout the Muratic should I add? I do loose chlorine during the day that is why I have started to get CYA in there as I was told by my installer the SWCG would look after everything! Which it has I have never had anything but clear water but I have the SWCG running at a hight level to do so and I don"t want to kill it.

Your pH is fine for right now, but you'll need the acid to lower your TA..here's the method that we recommend: http://www.poolforum.com/pf2/showthread.php?t=191

Once you get the TA down, the CYA up, and the pH rise slows down, your pool should be a lot more maintenance free!!

The thing I find weird is that my PH went down with my addition of Muractic yesterday but my Alk went up by 9ppm. Is this because of not enough airation? I only have one jet to use for this. If I add more acid will my PH not drop even more? Don't want my pool to be a chemical sess pool!!!

I don't think your alk went up with the addition of muriatic acid. Yes, if you add more acid, the pH will go down further. What is your pH and TA now?

[Mr.Mooks]

On Friday my PH was 7.9 and Alk was 167 ppm then I added 1/2 gallon of Muratic and 1/2 Gallon of liquid CYA got another test Saturday and the PH is 7.4 and Alk was 176.

My guess would be faulty testing....but you could verify that by testing same sample from two different stores.....

That is likely. I have put in the CYA in a sock so I am waiting for it to dissolve. I think I will add 1/2 gallon of Muratic tommorow and then I wait a few days and get another test. All I am realy trying to acomplish is to lower the runtime and percentage on my SWCG so it will last a few years. Everyones help on this site has been awesome. Thanks to all. After next test I will post results and proceed with the suggestions I receive here.
