It's good to know at what point to test the free chlorine. I made the mistake of testing after the carbon filter.
I have tested immediately after the contact tank, and it's 'off the scale'; my scale only goes to 3ppm.
The feed-pump that was installed is adjustable, but I've adjusted it to the minimum, and I've diluted the solution to 1:6.
According to my calculations, pumping @ 5.4GPM, with the Stingray feeder set at the minimum or approx. 10gal/day, the water going into the contact tank is @ 11ppm chlorine.
Should I simply continue trying lower concentrations, using trial and error, to obtain the lower free-chlorine ppm needed coming out of the contact tank?
