I recently replaced my single speed motor with a 2-speed and wired the SWG to produce only on low speed. Previously with the single speed motor, I would see very small bubbles coming out of the returns when the SWG was producing, and always wondered if I am losing chlorine from any bubbles that make it to the surface (and thus also losing salt because the chlorine that escapes does not recombine into salt). Now, with the SWG only producing at the pump low speed, I see much larger bubbles at the returns just sort of dribbling out of the return fitting, and a larger majority of these bubbles reaching the surface. Is this normal on a low pump speed? If so, aren't I losing chlorine and salt this way? (I did check to be sure the bubbles weren't air being drawn in from a suction line leak--the bubbles only appear when the SWG is producing.)
I've never used an eyeball return fitting (I already have long pipe runs and wanted to minimize pressure loss), but wonder if this would be a good idea to help dissolve the chlorine gas given the higher flow velocity at the return.
