I have been following the BBB method for my pool this year and it has been working great! My friend has a Summer Escape 15x42 pool (one of those blue ones with the inflated rim). Holds approximately 3200 gallons of water. The water is not clear and she needs some advice. I will be getting a water sample from her later this evening so I can tell her what to do. To my knowledge she has been adding bleach and putting chlorine tablets in the skimmer. I was wondering on a pool that size do I need to tell her to add CYA? Can the BBB method work for those pools? I am sure it needs a good shocking but just wasn't sure about the CYA and if all works the same with these pools?
