Why should I use granular instead of powder form?

26500 gallon vinyl above ground, bleach & boric acid. All chemicals are within troublefreepools.com guidelines and the water is stunning. I use algaecide 60 in my pool and the cost of $24 per quart online or $30 at the pool store is killing me. Any suggestions for a better price online or an...

I have two jugs of outdoor bleach that I would like to dilute. The bottles do not state the percentage chlorine. How much should I use to get a 96 oz. bottle of 6% bleach? 12% would be good too.
