This is my first year owning a pool in Arizona. I have talked to a few people around town and most have said they drain and refill their pool every 4-6 years. Some longer intervals, some shorter. Most have cited "chemicals way out of whack" or "too much dissolved solids" but didn't elaborate.
I just filled my pool (25,000 gallons from the city was $350 or so) since it was drained while the property was bank-owned.
Of course we have very low rainfall so natural dilution is very slow, and evaporation is very fast. We also don't typically close our pools for the winter.
I'm wondering if I follow the BBB method, if I will still eventually get to a point where it makes sense to start with fresh tap water, or if I could maintain the levels indefinitely here in Arizona?
