It is just money. I figure it costs about $300 a year to run the pump
and another $400-500 for chemicals. I spend 10 minutes a week dealing
with that and I check it in the middle of the week to be sure things
are going OK. Once you get the routine down, things are very
predictable.

And you live in Florida. I would have thought the costs were much higher.

Not having to "close" and "open" it each year makes the hassle factor
much lower. When the water gets cold for our 3 month winter, it just
cuts back on the chemicals I need. It just kind of goes to sleep and
snowbirds still jump in.
It is the summer with an inch or two of rain every few days that
screws with the chlorine.
