Does local Govt participate in spreading the stabilized chlorine deceit?

I don't say either Di-chlor or Tri-chlor shouldn't be used. I say they shouldn't be used when CYA reaches a certain level or when pH drops to a certain level.

Tri-chlor is great stuff for a new concrete pool that's curing. It can be good for leaving your pool while on vacation.

But, (and here's the "but") you need to test weekly for CYA, TA, FC, CC etc and daily for Chlorine and pH. So you watch them and when they hit the limits change what you are doing.

But you should be doing that anyway, regardless. That's just good pool maintenance (see my sig line)
