Left over aquarium gravel ideas?

[Al1ce]

Hi I have now moved all my fish to a new tank set up with sand, but have a huge bag of left over coloured gravel, does anyone have any ideas I can do with it, was thinking like doing a feature in the garden or something, Iv used some in household plants, incl the aquarium water because plants love it, if anyone has any ideas as don’t want to throw it away maybe I can get the kids involved in the garden.

Well, you seem to have already taken my sea. You can place it in the bottom of pots for drainage in potted plants.
