I just converted to a SWG from regular bleach this year. I have the Hayward Aquarite working great and all the plumbing and electrical is good. My chorine level has been steady for weeks now with bleach and was sitting at around 5 ppm last night.
I just dumped in my bags of salt this morning to get up to 3200 ppm, and an hour later I checked my chorine with my TF-100 test kit and it's at around 0.5 ppm. I just dumped in another 121 oz of 8.25% and will check again soon.
Is this common for the salt to increase the chlorine demand, at least initially? What else could be going on?
