Sailing_Faith Posted August 10, 2008 Report Share Posted August 10, 2008 I have had pools all my life, and have owned my current home / pool for the last 8 or 9 years. I just got a Hot Springs Sovereign tub, it is filling right now. What are the differences in managing the chemistry of the tub? Obviously I don't have a sand filter to backwash, the tub has 3 paper element filters (I have them out now, I plan to buy new ones rather then using the old ones). I bet the chlorine will evaporate much faster, since the water temperature in my pool makes a world of difference in the chlorine levels. Can I just test / maintain the water the same way I do with my pool? Thanks, Quote Link to comment Share on other sites More sharing options...

The spas are not as forgiving as a pool because of the smaller body of water and it is mostly covered a lot. You should not have any problems if had a pool, just keep them filters clean Quote Link to comment Share on other sites More sharing options...
chem geek Posted August 18, 2008 Report Share Posted August 18, 2008 The main thing that most hot tub owners don't think about is how the bather load is much much higher than in a pool (that is, the number of bather-hours per gallon of water). This results in much higher oxidizer demand of as much as 7 ppm FC in 350 gallons per person-hour of soaking. Most of the chlorine is consumed in this way. Yes, there is more that gets outgassed or breaks down, but this is still less than that consumed by oxidizing the ammonia and urea from sweat and urine.
