So you add chlorine and CYA initially and all the time...they "breath" out of your water with sun/use/temp, etc. Does CYA build up and then you stop adding it, or does it always need to be added? Is CYA required to get the chlorine to work?

Regarding PH, you get your PH set and then monitor it.

I get it that you stay away from copper under all costs or you have to drain the pool to get rid of it.

I won't need calcium as I'm vinyl liner. and....

What are tabs?
