I need a little advice. I have a D-1 AFS unit aka a "swim spa". The unit hold approx. 1700 gallons and keep the temp at 95 degrees, but I plan on lowering it to 80 degress for the summer. I've had the unit for 6 months and i'm still not sure how I should treat the water. My dealer is not very helpful. My problem is that all of the advise I've seen is for hot tubs that are at 100-1004 degrees. How should I treat mine? As a hot tub or a pool? Thanks
