zich6 Posted October 29, 2022 Report Share Posted October 29, 2022 I have 440 gal, HT and I live in North Idaho where December/January temperatures are frequently below freezing. I typically test the chemistry every two weeks, but if I lower the temperature to the minimum 80F can I get away for not adding chemicals/testing for 30 days. Emptying the tub is not really an option. I would appreciate any other advice. Thanks Quote Link to comment Share on other sites More sharing options...
Couch67 Posted October 30, 2022 Report Share Posted October 30, 2022 If you dont have one, get one of those floaters that holds bromine / chlorine pucks. Fill it up and turn the dispense rate to its lowest setting. I added a string to mine and loop it around one of the topside jet controls in the corner furthest from the filter, so its not in the most turbulent part of the tub and dispensing too much bromine.
