Hey Leon,
Yeah, I’ve been through the same thing. When I first got my saltwater system set up, I was constantly fighting with the levels and especially the chlorine and pH. Turned out my salt cell needed cleaning way more often than I thought, and once I got on a regular schedule with that, things started to even out.
Also, check if your stabilizer (cyanuric acid) is in the right range. Mine was too low at one point, and the chlorine was burning off super fast in the sun. Took me forever to figure that out.
It’s definitely not “set it and forget it” like some folks say, but once you get it dialed in, it’s much smoother. Hang in there, it gets easier.
