I will soon be into my 3rd season with my new pool and have used the BBB method from the beginning. Up until now, I have only used my SWG and bleach for chlorinating and used 100% CYA granules for adding stabilizer. I'm ssuming that I will need to raise my CYA level after I open this spring due to vacuuming to waste. What are your thoughts on using dichlor to raise the FC to shock level and gaining the benefit of some "free" CYA? Or, is it better to continue using just bleach and 100% CYA granules?
