    How often do you need to change your water?

    So I've maintained my pool for 3 years now. However, I realized that I never change my water!! I balance and chlorinate using the BBB method? Is it even necessary to change the water? How often should the water be changed?

    From what I've learned on this site the only time you need to change water is to get you CYA in balance or for high calcium hardness.

    The only time I've changed my water in the past 7 years was out of necessity. The liner had a tear that wasn't worth patching. I even did a baquacil conversion after the first 2 years of owning my pool and never changed it out. This method is tried and true!

    No reason to change your water if it's properly maintained, some times CH gets out of control (CH doesn't go away) and tends to be in fill water, as water evaporates it (CH) stays behind.
