I've used the Grunge in a number of tanks. It does add some diversity.iamjosh said:They have a special running right now 10 for $100, Plus 2lbs of Grunge Plustm.
I need to get the bigger tank so I can start trying out these random things, need better lighting too.
More Info @ www.garf.org.
I think I might try ordering some of the Grunge, anyone tried that stuff?
