1. I stuck with just testing pool water as I was able to actually get the tests to work properly after dumping 1/3 of my pool and refilling. Numbers are:

FC: 0ppm
CC: .2ppm
PH: 7.0 ppm
Total Alkalinity as calcium carbonate: 100ppm
Calcium Hardness as calcium carbonate: 250ppm
CYA: 80ppm

2) Unfortunately, many markings are worn off. I can tell you the pump is a jacuzzi pump, but I don't have a model number, and the filter tank is model number jsal180, but I can't find a brand. They do appear to match so I am guessing jacuzzi

3) Lets only work on getting the water balanced and clear (it's only slightly foggy right now..can still see bottom fairly clearly)
