I am looking at the Caldera Martinique (It's for indoors and needs to fit through a 6'8" opening. When discussing filtration/purification the dealer discussed many of the benefits of the mineral/bromine Frog system. He said that other than an initial pH set, I didn't need anything else. When I asked about Ozone, he mentioned that it wasn't necessary but it was only about $100 to add it.
Any thoughts on the with/without ozone on an indoor hottub?
Thanks in advance
