The site has them for sale and states they are good for fuges and that they lower nitrates. Anyone know anything about them? If they do lower nitrates, I wonder how many it would take to make a difference?
Well, for 6 bucks, guess ya can't expect much. Probably takes 100 of them to lower nitrates 10ppm......in a month. I actually went ahead a bought one and stuck him ( or her... ) in my fuge. It's disappeared now:notsure:
