I'm a converted BBB pool owner and have learned so much from all of you. Thanks to all!! I do have a question though: I ran a Nature2 cartridge in my pool for years and bought one this spring (among $250 worth of other junk)to put in my pool but this was before I discovered the triple B method. From what I've read I really don't trust JUST the N2 cartridge and a .5 FC level to sanitize my pool anymore so I'm running my FC between 3 and 6 (for a corresponding CYA of 40) along with the N2. Am I being neurotic and just wasting bleach by keeping this FC level in conjunction with an N2? Could I reasonably keep a lower FC level because I'm using the N2 also?
I don't plan on purchasing a $100 N2 cartridge next year, just going with the triple B. It just makes so much more sense to me.
One other thing. When balancing out your pool after a winter layup, what is the first thing to get in line; pH, CL or CYA?
