Bullfrog @ease Classic Mineral(Blue) & Smart Chlor(Silver)

These cartridges used to work properly but recently I’ve noticed the water isn’t balancing correctly despite draining and starting with freshwater. The cartridges seem to be lasting a fraction of what they should be and what they previously were. I’m not sure what’s going on with them, but something has definitely changed. and for the worse.

Easy to use in our Bullfrog spa. Cuzzi has a great selection and a good web site for repeating the order every three months.

Awesome
