I have an 18×45 round above ground pool. I can’t get the hard water to go away. I always have a high ph also. The pool is in direct sun all day. Should I refill it?


The high pH and hardness together cause problems - cloudy water, scale, etc. If problems persist, it is a good idea to drain and refill the pool. However, often times a complete drain and refill is not necessary. You can drain part of the water and refill with fresh water to adjust the hardness down and make it easier to control your pH.
