Hi,
As I navigate treating the water in my hot tub, I noticed my Artesian Captiva is listed on their website as a capacity of 400 gal. When my local hot tub store delivered the tub they told me to set the Spa Frog to "2" which is for 300 gal hot tubs. Assuming it's filled to headrests as stated in the manual, should I base my calculations on 400 gal.? If so, any thoughts on why the store would be recommending the wrong Spa Frog setting?
Thanks!
