Please help me. My pool is somewhat cloudy. i got a test kit it said my alkalinity was high (270ppm; but the pH was ideal 7.6). went to pool store and they told be to slug the pool. I added 2 1/4 cups of ph down ( in 1 gallon water slurry) to a 1250 gallon above ground pool. It dropped the alkalinity to 120ppm- Great but now the pH was below 6.8. I had to raise the pH back up with pHUP (sodium carbonate) and know the pH is 7.6 but the alkalinity it back up to 270ppm. I basically am going in circles. We are on well water, i added calcium stabiliszer and chlorine shock but that is the only thing that has every been in the pool. It is also usually covered. How can you decrease alkalinity without decreasing pH or once you decrease alkalintity how do you raise pH without raising alkalinity again? Can you help me???? someohow suggested airating but ia ma not sure how to do this either. thanks
