Got the K-1766, thanks, @JamesW. It's at 6000ppm. It looks like the pool was being filled with conditioned water for quite a while.The K-1766 is a good choice.
I'm guessing I need to partially drain it down to an acceptable level since the salt won't evaporate with the water. Is the equipment, plaster, or tile at risk with the level being as high as it is? How quickly should I plan on doing the draining?
I also got the K-2006C kit, but since I'm looking at doing a partial drain/fill I don't think testing levels quite yet is the right move, should probably do it after salinity is good, then worry about chlorine, and whatever else I discover I need to add.
Does this approach sound good?
