New pool high ph

[Calleblanc77]

I am a 1st time new pool owner of about 2 months. I am experiencing my ph rising continuously. Is this normal and will it settle down eventually for this plaster pebblesheen pool? All my readings seem good. I have a waterfall which I hardly run and a spa spill over that spills over into the pool which I run the pool filter pump 8 hrs a day on low 1725 rpm so it is more of a tricle over. I'm having to add a pint or two of acid about every 5 days to try to get ph down from 7.8-8 to 7.4-7.6.

I just took my readings using a taylor k2006 test kit

FC 1.6
Cc o
TA 90-100
CH. 300
Cya. 50-55

A pint or two every 5 days is no big deal. A new plaster pool will tend to have pH rise for the first year. A spillway will also cause the rise. Just stay on it and the TA will slowly drop and the pH will stabilize.

I agree with John. That isn't an amount for concern at all.

Thanks for the responses. I was thinking that and hoping to hear the same responses you gave. I am hoping it will stabilize at some point but in the mean time I am having fun running the test myself and seeing the effects of adding chemicals to get the desired results I want and need. I will just stay on it a couple times a week. One thing I have learned and am a true believer of is that a good test kit is essential to doing this yourself. I have taken two samples on the same day to two different pool stores of the same chain and got completely different results. I don't trust the pool stores readings!

What you have experienced with the pool store's different test results is not uncommon. Trust your testing and keep all your parameters within TFP recommended ranges and you'll be fine.

That's terrific! A lot of people here wind up feeling the same way and find it pretty rewarding testing and doing their own chemistry. I do for sure, and actually enjoy it. Unfortunately, you story with the store results is too common, but it sounds like you know all about that now. Glad you're aboard, and we hope you continue to stick around and enjoy the forum.

I was adding 2 quarts of MA a week after my fill. Now about 2 cups.

Is that FC a little low?

The manufacturer of the uv / ozone system recommends to keep it at .5-1ppm. I'll give it a try and see what happens. It has only been about 3 months but everything seems good so far and it has been staying under 2ppm. I am going to get away from the trichlor pucks and go liquid chlorine not to mess with my other readings.

Sorry. Didn't notice the Ozone system in your signature (it's a long one). Outta my league here!
