This is my first year ever having a pool. Wow wasn't prepared for everything it requires. I finally got the chemicals where they should be...or so I thought. I have spent hours and hours reading and researching everything that needs to be done. I went to my local ace hardware and bought their brand of test kit and it seemed to work great, but I didn't know about cya until I got so frustrated adding chlorine every day only for it to disappear in a few hours. I didn't have the funds to purchase a good taylor kit, so I bought the hth kit so I could test the cya. I ran all my numbers on both kits just to see if they were similar. All my numbers were almost exactly the same except the alkalinity. I have ran this test a bunch of times being very careful that I'm doing it all properly. My last test showed: ace brand: 110 and hth: 180
Very different numbers. Why is it doing this?
