ok guys I am now out of bleach so I am heading back to the store. I had bought about 40 gallons of bleach for around $120. Starting to run low on cash, but I know I'm too far ahead and invested now. FC is some where around 14, ran out of reagent to test it, so getting more of that as well. Which is my best option for chlorine, should I continue buying bleach or switch to something that packs a bigger punch?
