So we went to our new-to-us house for a couple hours today (we move in tomorrow) and I tested the free chlorine at 15ppm using a 25ml water sample. Being new to this and sensing this was way too high I tested the water again using a 10ml water sample and that one came back at 17ppm. I'll do a much more thorough test of the water tomorrow when I'm rested but that seems WAAAAY too high. I glanced at the Pentair IC40 SWCG and all the lights were lit so I think the pool care guy the previous owners used had it set at 100% which seems way overkill because the water temperature is 55. The SWCG was set at 100% when we looked at the pool a couple weeks ago too.
I tested the salt and it was around 3,600 so at least that is OK.
