just curious. I haven’t researched filtration yet. Thanks.Are you asking if the rocks will help with filtration straight from a stream? No. Is there a rock that you like and want to use in your tank because it looks cool? Or ?
Then as @Kristopher Sekely said, no. Rocks in a marine tank are used as part of the filtration. Bacterial will grow on the surface areas of the rock; the more porous the rock the more surface for the bacteria to grow. That’s a real simple explanation but that’s the basic idea.just curious.

Bacteria also grows on freshwater rocks and part of the filtration system. But you can use freshwater rocks as filtration on saltwater tanks, is like adding dry rock.Then as @Kristopher Sekely said, no. Rocks in a marine tank are used as part of the filtration.
