Does local Govt participate in spreading the stabilized chlorine deceit?

As Carl says, if you measure your pool's water chemistry regularly, then you can stay on top of the CYA level.

You can measure your CYA to your heart's (and Taylor's) delight day in and day out, but if you keep using trichlor and there's no significant fresh water exchange in your pool, your CYA will keep rising up to a critical point. Ain't I singing to a choir here?

In fact, a vast majority of state Health departments do not allow trichloror dichlor use in commercial pools (and their jurisdiction is over commercial and not residential pools.)

Who doesn't take appropriate actions when testing reveals a problem?

We've had folks here who would only take half our advice (the easy half) then run to the pool store for re-assurance and dump 16 different useless or dangerous chemicals in their pool, then come back and complain we weren't helping them!

At some point, my patience ends and I tell them I cannot help them...
