Chlorine Tablets in the skimmer

Yup. So either my diffusion theory is wrong or such in-line chlorinators have one-way valves to prevent this or they in fact do have similar issues from diffusion, but possibly not from a "blast" of acidity since I think they are placed at the end after the filter and heater, similar to an SWG.

Inline chorinators are plumbed AFTER the pump and heater so the chlorinated water is returned to the pool and does not go through the equipment. They also do not 'dispense' the chlorine unless the pump is running and many have check valves before gthem to prevent the heavily chlorinated and acidic water from backing up into the heater. The actual chlorinators themselves are made of materials that are desgined to stand up to the low pH and high chlorine levels (such as speical o-ring materials, etc.) but they still do show degredaton after a period of time.
