I am getting a oxygen stone to go along with my medical oxygen tank. I got a 3/4 full ME tank that has about 500 liters of oxygen in it, so I got plenty of O2 to work with. I am trying to decide between a 0.5 vs a 2 micron stone. I am going to get either with a SS wand so the only question I have is size. I know a 0.5 stone is much more efficient but I don't want to have issues every batch with a clogged stone. I plan to boil it after every use for 10 min then store in a strong mix of starsans or in vodka until I use it again. I still hear alot of people complain that their stone clogs and it seems they are using a 0.5 micron. Does anyone have any experience or imput? Thanks!:rockin:
