I just got a new hot tub a month ago and am working through figuring out a maintenance routine. I have a @ease floater system with chlorine. I have upped the dial from 1 to now 3 and still is showing low on the test strips on my weekly testing. i have been adding 2oz of chlorine then but the next week it is back to showing too low. Not sure how to test what the actual levels are or what they should be. Any ideas? also my ph keeps creeping up every week. I use it 6 days a week myself for maybe 30/day. I have the air jets running and I know that can increase ph but I don’t think I am using it enough to have it increase so much. Any tips?
