Hey, the SWG arrived Friday and was installed last night, turned on today. Unfortunately, I did not have any salt testing equipment or stips so do not know what my ppm is at - I spaced it out completely and there is no place locally that sells that so I will have to order - we have always had salt in our pool just for the feel of it so this is complicated.
1) We had about 120# last year mid summer (so some water added/some pumped out during seson) all before draining down below skimmer for the winter.
2) We added water at opening this spring along with 160# salt -
3) THEN we have proceeded to get over 13" of rain into the pool and pumped that much out.
4) I added 120# of salt last night and plugged in the unit today to give it a test drive. Surprisingly, it did not give me any error codes (Hi salt or Low Salt) So I'm hoping I am right in my range anyway of 2500-3000 ppm. I do have more on hand in case, but wanted to be conservative and go up from there sparingly if I have to.
Tomorrow, I will actually run it for the full 12 hr span to see how it works. It ran for 3 hrs today and appeared to be operating well. My FC was standing at 3ppm at covering tonight. The water was a balmy 90deg, but now its cooled off and raining so we'll have to see how it goes. I am anxious to see how well it does on a regular basis.
Leaving for vacation tomorrow night with a teenager in charge, so maybe just leave it on auto with an emergency backup jug of bleach for him? He was given instructions on what the errors codes are, when to check it and what to do if he can't figure things out. (add bleach/cover, turn everything off if there are any problems and close the valves if there is a leak)
