I've never owned or maintained a pool or spa and I'm having one delivered next week. I've been researching for weeks and have settled here. I appreciate this website as I also want to use a minimalist approach. I've received my k-2006 and read the waterproof book. My plan is to use bleach and ozone after the water is balanced.
Question one: Is CYA required? I don't have an issue with daily dosing of bleach.
My spa will be in total shade all the time, shaded by the house; also covered of course when not in use. If I can get away with one less compound, I'll do it.
Question two: Is MPS required? I upgraded to a bigger ozonator. Is it possible to maintain low CC with bleach and ozone alone?
Question three: What advice do you have for one who does not wish to use borate?
