Climate: very moderate, maybe 3-4 mild freeze days, temps in the upper 20's. It's too cold to swim, so what is the most cost effective approach.
Changes this year: replaced single speed, 3500 rpm pool motor with variable. During the swimming season can only dial it back to 2500 as we have a solar heater. Plans were to save some money this year by turrning the value on the solar and reducing the speed to about 1200 rpm for 1 turn/day.
We looked at pool covers, but they are so expensive and hard to manage, we decided not now.
Questions:
1- if drain the solar heater, in the spring will the pump fill the tubes back up in the spring?
2- Why bother, why not just turn off for offseason and shock in the late spring?
3- In ground concrete pool, would it hurt anything if the water evaporates duing the off time?
4- is there a better approach?
Thank you in advance for your ideas. This is not urgent as we have a good month to month and half of
swimming left, but trying to think ahead.
[Haven't run full numbers in a bit. Chlorine is kept between 5 and 7 ppm by using the 10% bleach solution. My testing chems must be getting old. Test yesterday morning was 1.5 FC and so added 2 gallons Normally that would boast about 2 to 2.5/gallon. Today it was high at 10.5. I lose about 1.5 to 2.0/ day. We have much scaling on tiles, so not paranoid about PH. Last week it was 7.4, guess now is about 7.8. CYA is about 60. Other numbers were not out of balance, so stopped testing.]
