Let's put that SLAM FC into perspective:
Under the
FC/CYA Levels is a link to Chem Geek's version of the chart that also shows the target FC levels without CYA. From that you can see that TFP's SLAM FC level is equivalent in terms of active chlorine concentrations (HOCl) to FC 0.64ppm at CYA 0ppm. No, there is no typo, the decimal point is at the correct position.
That means that an FC of 4ppm without CYA, where no equipment manufacturer blinked an eye would you bathe their product in it, has more than 6 times higher HOCl levels than TFP's SLAM FC, like for example FC 16ppm at CYA 40ppm.
I think you can draw your own conclusions from that.
It is much safer to run your robot in your pool at proper SLAM level, than to borrow it to the public indoor pool round the corner, that likely operates without any CYA, and maintains FC below 4ppm.
