I have an assortment of Dried Natural Ocean Reef. I have it all in a plastic bucket ???? and put it in the scale. It came to an even 11kg. It was once used for a marine tank, but has been dry for over a year.
I’ve taken a few photos of some rocks to show you the size difference. First photo is of some of the rock being used in the tank.
