Scuba Jules Posted July 2, 2018 Report Share Posted July 2, 2018 I've read alllllll of the "How To" threads, used the search function, etc. I can't seem to find this addressed in water chemistry. This is my first spa and I inherited it from the previous home owners. (Yes, I have decontaminated it.) In the winter I will keep my spa at 100 degrees, but during the warmer months I find it refreshing to keep it below 90 degrees - even 80-85. In terms of chemistry (pH, Cl, Alk, etc.) what changes with this? I know this is a broad question - I just don't know what to be more specific about. Thank you.

gthomson Posted July 4, 2018 Report Share Posted July 4, 2018 I don't have a PHD in chemistry and struggle to understand all the responses to these posts but I wouldn't think there would be any problem with keeping the tub at 85 in the summer. My pool rarely goes above 85 and the water is usually really clean as long as I check it every month or so. The only thing I find with my tub is the circulation jets seem to stop when I set the temperature too low which is not good. I keep my tub at 94/95during the winter and then jack it up a few hours before I go in just to try and save a bit of money on electricity. Not sure where you are but Canada gets pretty cold in Jan - Feb and the cost of electricity is high. Hope that helps Quote Link to comment Share on other sites More sharing options...
