Spa Frog @Ease Floating Sanitizer System

Found what I needed online and it was super easy ! Arrived quickly as well

Easy to use. Takes guessing out of adding chemicals.

The Sundance filter system is not customer friendly. You can only buy the filters that go inside the tub from an authorized Sundance store. It is hard to tell when you need to replace the filters. They say 4 months for the blue filter and once a month for the smaller gray ones, but how do you really know. You don't. I ordered the float style ones, first time by accident as I had yet to figure out this system. It turns upside down when used up. This is my first time buying the blue one, again it took me some time to figure all the details. However, I am looking forward to using the ones that turn upside down when time to replace. I am not bothered by the filters floating around. I am bothered by Sundance and their forced purchase plan. However, the great news is that both filters - proprietary and "upside down turners" keep the tub very clean. My old tub - also a Sundance, I used a lot of clorax to keep clean. My new tub with the UV light and the frogease filters is super clean as long as you change the filters and light (once a year) in a timely manner. Now, I will know when a timely manner is. Thank you for the option to never have to buy the proprietary filters again. Filters are pretty expensive, but they do a good job.

the system works as advertised, keeps my water crystal clear with only adding shock and a little ph up once a week. the chemical strips makes accessing the water condition very easy. The cost is more than using regular chemicals, but you have to constantly monitor it, with the at ease system I only have to check and add chemicals once a week. It keeps me from having to change the water and filters, I have not had to do that for over 6 months, so the extra cost is worth it to me, as my spa is always ready to use.

Love the Frog Ease products. Have used them ezxclusively for 4+ years and our hot tub stays clean and bright. Use it almost every day, winter and summer, to ease arthritis pain.
