I think this website is the greatest online pool resource around. I have learned a ton of information here about pools and the people here have saved my a!$ many times when I've had problems
That being said, I don't follow BBB at all. I just don't have the time to be fussing with liquid bleach every day. I go to work at 6:30am every morning and I get home at 7:30pm. Pucks put into a chlorinator are the greatest thing in the world to me.
I have an inground 16x32 vinyl in which I haven't changed the water in about 4 years. The only reason I changed it was because I replaced a 25 year old liner.
I do have the best recommended testkit here and I do test once a week.
My free chlorine levels are usually spot on, and my cya never seems to go up. I dont know why, but it never even measures on the chart.
Every other week or so I drop 2 bags of powdered shock (I believe cal-hypo) in as a maintenance blast but I dont even think I need it. I do it as a "just in case"....
I do watch the PH very carefully cause I dont want to lose the heater or burn out people's eyes and stuff, but my pool is always crystal clear.
Ive been reading this board for years and I know that the cya to fc levels are extremely important, but it never seemed to be a factor for me. It has to be much more than luck. Ive been doing it this way for many many years.
I do run the filter 24/7 just because I dont mind the small change to my electric bill each month and I feel it keeps the water extra clear. LOL.
So I guess what I am saying is other than the ops friend's lack of concern of the PH, I agree with everything else
