    Why is CYA desired when using SWG in spa?

    I know you guys have established good practices. I've run my tub for 1.5 seasons now, and have just started to get serious with doing it right (just got in my Taylor K-2006). Todays #s: TA 40 PH 7.4 FC 2.4 CC .2 SA .43 no CYA guess it's time to get some...

    Why is CYA desired when using SWG in spa?

    I see. So SWG is irrelevant here? (Don't currently have one). But I'm currently running an ozonator. Does it alter the oxidation factor? (Maybe less CYA required). Also, what is effect of oxidizing the cover? Does the bottom vinyl go bad before the top?

    spas using stenner or liquidator

    Am thinking about auto-chlorinate system to lessen daily FC checks. Is SWC currently the favorite for use with spas? I have a 650 gal system with ozonator. It gets maybe 4 person/hours usage per week (in winter), 1/2 that or less in summer.

    Why is CYA desired when using SWG in spa?

    Why not just up the setting on SWG to compensate for greater fc loss?

    salt water chlorinator

    Has anyone heard just how long these technichlors last? It seems they don't have replaceable plates, so operating costs will be higher than similar units (with replaceable plates), right?
