I live in fort lauderdale and run my pump 6hours/day. I also use my pool year-round BUT i do not have a heater. I believe if you cut the pump back to 8hours/day your pool will still be beautiful and in our weather it will be plenty warm this time of the year with or without the heater. plus when it hits the low/mid 90's and the humidity is high the colder the water the better for me at least!!! good luck hope i helped at least a little bit
