    cya question

    I add water almost every other day because of all this hot weather. I can't get my cya up. I put in the recommended amount wait a week and it either stays the same or drops.

    It does not drop below 50 and I am holding fc steady at 3.5ppm. Is it because of adding so much water?

    Are you sure you don't have a leak? How much water are you losing? No amount of evaporation would cause a loss of CYA, but a leak sure would....

    I do not see any signs of a leak anywhere. The weather has been in the high 90s and a few days of 100 plus degrees. My pool is in direct sun,no shade so we have been getting a lot of evaporation and adding new water.

    I get my cya from ace hardware and it says its 96%. How would you know if you had a leak underground?

    Does your pool drop more than 1/2" every day?

    Re: cya question

    There is a test for leaking. It's called a 'bucket test', and it's as simple as placing a bucket of water on a step or something so that the top of the bucket is out of the water. Mark the level of the water inside the bucket with a permanent marker. Then mark the level of the pool water on the outside of the bucket. Check back later. If both levels drop the same amount, it's due to evaporation. If the pool drops further, you have a leak.

    If your daily loss is like you say, do the bucket test and confirm that you have a leak in your pool.
