Natural Lava Rock, 3 pcs hand selected.
This extremely porous natural black lava rock is sourced within the US and procured by us for the purpose of providing maximum surface area for beneficial bacteria colonization while offering aesthetically pleasing hardscape decor.
Each set of three rocks is hand picked by us to complement your aquarium. The rocks are natural and will differ slightly from those shown in these pictures but they will be roughly the same size about 3-5" each.
