I just learned about N2.
I think that I am going to be using bromine with my spa. Does the frog system assist with this. Everytime that I thinnk that I am finally begining to understand, something new I learn.
I have ozone coming as well, so with this frog system assist and can I use it with any brand of tub. Just a little input on this would be great. I have not heard to much about it here.
I love this site it is so informative.
