Previously, I've used rocks from a nearby field/ditch, etc to decorate an aquarium, before hand I pressure washed them and then threw them in. Didn't seem to have any negative effect on the tank.
Anyone done similar things? If so, what methods did you use to clean/sterlize them before adding them to your tank?
