Thanks for the responses. I thought I recalled reading on some posts here that around 1.5ppm chlorine was ideal for the SWG. At any rate, the unit is not generating chlorine right now, as the setting is at 0%. It simply is controlling the pump run time, which is why I was wondering if setting the unit to x% (maybe 30-40%) would help balance out some of my chlorine issues. If I understand correctly, I thought part of the generation process involved the elimination of chloramines in the cell, thus brining my "good" chlorine levels more in line with where they should be. I know that I still have some unknowns as I'm patiently waiting for Ben's kit to arrive.
If the HTH algaecide is causative of the irritated eyes, how long should it be until that dissipates? Again, it's been almost 3 weeks now since that was initially added.
