Well, tell me if my math is wrong, but from your figures (using 60000ppm for 6% Clorox):
.06/35gal = .0017143...
1:128 = .00001339...
or 13.4 ppm
So I figure the concentration/solution that my injector is doing right now is approx. 11ppm. Previously it was maybe twice that, before I reduced it, using a trial and error approach.
Thanks ditttohead, for helping me to understand how to figure this!
So 10 to 15ppm is the common concentration in most systems?
How would I know if I could do less than that?
Here's another whopper:
When the system was first installed, no one thought to install the carbon into the tank. The installer blamed the supplier, and the supplier blamed the installer.
It ran this way, at perhaps 24ppm, for two weeks (maybe at even 3 times that concentration for a few days).
Any ideas what kind of damage was likely to have been caused to the rest of my system with the high chlorine concentration, esp. to the resin in the softener tank?
If the resin fails, will it be obvious to me, perhaps in the shower?
