We've decided to try using a bromine floater as we are just about out of the powdered bromine that came with our tub. We have a floater in a vacation rental condo we own but it is a bigger tub, a HS Prodigy, and used as a short term ski area rentals and it is professionally maintained.
I'm looking where to initially set the floater opening for our personal HT, 250 gal. 102F, usually just my wife and myself mostly daily use. Occasionally our daughter and grand daughter come for a visit, a day or 2 every several weeks. The graduations on the floater look to be 1/4" apart and numbered 1 to 13. I thought I would check the bromine a day after putting in the floater and adjust from there.
