GARF grunge


salt water dummy
i know this stuff is great for the reef, but what about a FOWLR? what does everyone think about this stuff? i've heard good and bad, just wondered what you guys thought!
I have heard both great and horrible things about it, I cannot speak from experience so Ill leave my comment to that.
From what I've seen,its over priced.But thats just what I've seen in other tanks.
Myself,I've never used it.
It won't hurt anything in a FOWLR tank, but if you have predators they will probably eat whatever animals come with the grunge, which is an expensive snack.
