Agreed I think this stuff is just another snake oil.
^ Yeah I know. It was recommended to me by my LFS very trusted LFS about 4 times in the past. I have worked with many of them in the past and know them all very well. So I know they are not just trying to sell me crap. A few of them use it on their tanks and said it does help, do I will see. At under $5 for a bottle it does not hurt to try. And the AA's they recommended to me over a year ago really work and I still use it.
