Hi Everyone,
My wife and I will soon be purchasing our first hot tub. This is all brand new to us, and I wondered if someone could help us with a couple of questions on water chemistry. We plan on using hydrogen peroxide for our tub, so obviously I know we will need to test for those levels. I believe the level should be somewhere between 50 and 100 ppm. I am wondering what else I need to test for. The two things I can think of are water hardness and PH level. Is there anything else I should be testing? Thank you.
