I’m so close to using my new hot tub that I can taste the chlorine! Today I had the 230 line hooked up--the tub is filled and hot --everything is a go except for the chemistry. My dealer offered to test my water to suggest a chemical regime so I thought I would hold off one more day for precision sake. My question is, going forth what is the best way to test the water? The tub came with some strips, but I’ve heard there are more accurate tests. What do you (all) use?
