new spa; sanitizer questions

[paulitzlee]

I may need to get a new tub.  Mine is 30 years old, and the heater doesn't appear to be working.

Are most new tubs salt water compatible?  Nature 2 compatible?  Ozone, ion compatible?  Are the spa brand and the sanitizer independent of each other?  Or are you locked into a sanitizer method with a certain brand of spa?  Bromine gives me eczema, and it's hard to keep the levels high enough to sanitize and low enough to not irritate my skin.

Thanks!

Hot springs have the ace system which is salt and there are aftermarket generators available for other brands.  All tubs are nature 2 compatible.  You can order any tub with ozone. No you can use what you want for hems in any tub
