FROG Serene Replacement Mineral Cartridges for use with Hot Tub FROG Serene Floating Sanitizing System - Prefilled for Quick & Easy Hot Tub Maintenance - 1 Pack

Q: does this cartridge affect total alkalinity?

This only affects total alkalinity in the way daily chlorine additions would.

Q: Do these cartridges come in chlorine instead of bromine?

They come in either bromine or chlorine. I use the chlorine cartridges.

Q: Can I set bromine cartridge to zero and still release bromine.

Great question: I believe that some bromine will inevitably escape at the setting of 0. The amount may be negligible though and if you are wanting a slow release that has an actual affect, consider setting it to 1.

Q: Do you change the chlorine and mineral cartridge simultaneously?

No. The mineral cartridge is probably good for about 2 to 2 and 1/2 times longer than the chlorine cartridge. Obviously it depends on your settings.
