Hi All,
I read a post on another forum and Hot Tub Aficionado said "I like the ozone, AG+ and MPS method" as opposed to the spa frog. My Caldera Niagara has the frog system and ozone. I'm not sure what AG+ and MPS are but would like more info if anyone can help with that. I am currently using Bromine because it came in the starter kit but would like to use chlorine (I think) once that runs out. If I switch to chlorine do I still need the mineral cartridge?? I'm looking to treat the water as inexpensively as possible but would like simplicity as well. Is that a pipe dream??
Thanks,
