We live in the central valley of California, where the 4 year drought presents many issues, practical and ethical, for pool owners. There are restrictions in place on new pool fills, and refills, and limits on lawn watering.
I swim 4-5 times a week; no other users. Evaporative loss means running my fill line around 20 minutes, twice a week, which is just about what the lawn gets. We are on a private well, with hard water. The CH in the pool is getting very high, >500, because of constant addition of hard water, with no dilution from rain water. So, two questions:
1. Any ideas to reduce evaporation? I'm reluctant to use a pool cover, because of the hassle of putting it on/taking it off, to go in the pool.
2. Any ideas about the hardness issue? I can't drain the really hard stuff, and replace it with the less hard well water, for obvious reasons.
Last summer, I started thinking about demolishing the darn thing, but keep hoping for rain.
