I am in the process of having an inground pool installed by next year (may make it this year). In the past 3-4 weeks, I have become addicted to reading the post. At first is was for ideas on equipment, types, etc. Now I am enjoying reading peoples water issues and trying to predict the answers. Without a pool I have nothing to compare it to, but at least my logic is going that direction. I watched my dad spend thousands of dollars on his hot tub chemicals. I believe the BBB method makes sense, because I heard all the different directions they sent him with chemicals.
BTW, growing up I lifeguarded at a public pool. I can remember changing out the canisters of cholrine gas. I also remember we had to do it in 3's. One had to stay outside in case someone passed out. The BBB method sounds easier.
