Autopliot SWG problem after refill

[PatL34]

I would add some more CYA to bring it up to 60 -80 ppm. You may have chloramines at this stage and the SWG is working its tail off trying to destroy these. If you smell chlorine near the pool, it means you are smelling the chloramines.

The extra CYA will help the Chlorine to inactive until it is needed.

Hope this helps.
