I am new to pools and just getting started with the bbb method. so far my pool looks great, but seems like im buying a lot of bleach. Is it really that much cheaper to use bleach then just normal chlorine. I get 1.42 gal bleach at walmart for 2.50 at 6%. I can get agua chem for around 6 bucks whick is 12%. I dont know how big that bottle is so I will have to recheck unless someone else knows. That works out to be 3 bucks for the chlorine being its twice as strong. Not a significant amount of difference for me to have to add more chem and lug more stuff around. Can someone give me the benefits to the BBB method.
