My pool runs on 60 ppm TA because that's the level in my fill water. Since all values hold well and I have no pH fluctuations, I leave it alone. My pH stays at 7.5. If yours tends to drop then you could raise alk to 80 and see if that helps.

Thank you for filling out the Pool Chart! It makes it so much easier to respond to questions.


ok, I will get more stabilizer. I guess that means the test kit is reporting correctly.

My PH has always been pretty steady, 7.2 to 7.4, but in years past my alk was higher than 60.
We add about 1 foot of water each year, I guess around 4,000 gal. Maybe the city water dept changed their alk levels.

I have raised ph by aerating on occasion. As you say, since ph is holding steady, the alk probably doesn't matter.

I just discovered the pool chart. Great idea. This whole forum is a great idea. I just remember my first trip to the pool store years ago before I found this forum and getting a printout of all the $tuff I needed to buy and not understanding any of it.
thanks.
