Hi Artcan!

Are you testing your water for more than pH and chlorine levels? If you are using tablets they are probably adding stabilizer, aka, CYA (cyanuric acid), or, possibly, calcium. This is not bad IF you are monitoring and tracking it weekly, but tablets may run it up farther than you want or expect. However, while PoolSean is far more expert than I am, I can tell you that salt systems frequently require much higher stabilizer levels than we normally recommend for non-salt system pools. This is not a problem or an inconsistency: SWCGs state in their literature that stabilizer levels are optimal in the 60-90ppm range, depending on the brand and model. 80ppm seems the usual. You'll then need to maintain a chlorine level of 5% of that...Stabilizer= 80ppm ==> FC=4ppm.

I don't know how you can get the kind of test kits we recommend, primarily the Taylor K-2006 and Taylor K-2006C, because there seems to be an issue exporting them to Canada, but you should have stabilizer testers easily available there. I hope.
