Ever since I installed the new ozonator parts,the water quality has been outstanding!
I can definately tell a difference from before,and after.
Installing the rebuild kit,was one of the best purchases I've made for my tub.
I highly suggest to other peeps,to use an ozonator,and to rebuild/install a new 1,every 3-4 years!!!
The ozonator in my spa is a Del-CD 50,which is a Corona discharge system. My understanding of it is,it's somewhat like lightning,and disinfects/kills bacteria.(correct me if I'm wrong) Having a working/functional ozonator aids in chemical usage,and provides peace of mind in regards to getting cooties from your spa.
