I saw some videos and read some things on the BBB Method that said that ordinary household bleach will work fine for pool use, but from what I've gathered from online searches, the 12.5% sodium hypochlorite liquid I've been buying is less expensive (per gallon) than a gallon of Clorox at Home Depot (but I have to buy 5 gallons at a time and put a $10 deposit down on the jugs.)

Is the recommendation to use regular Clorox based mainly on prices offered at HD-type stores versus what's offered at most pool supply stores? Is the hypochlorite I've been using OK to use, especially in a vinyl liner pool?

Thanks for helping out a newbie!
