I bought some 111 from a local janitorial supplier, not realising at the time.
Gardiners had run out.
Dont know what the difference is but performing the same for my system.

Im just wondering if 111 is regenerated and 115 is virgin ?

In hot weather when not using equipment over the weekend if water is tested at the brush it sometimes reads a bit high first thing in morning try running the pumps for a few minutes to clear the water that has been static in the hose reels etc then test again you may find that the reading has dropped back to where it should be.
