how many seasons (years) will this reagent last stored indoors, climate controlled?
i read somewhere that storing it in my fridge will prolong its life. is this true?
I ask because I bought a 16 oz bottle. obviously that will last me 4 or more seasons, depending how many times I mess up and have to SLAM..... which I hope isnt much.....
also, how do you know if it went bad? does it react different or does it change color?
