AquaGlow Smooth River Pebbles Substrate (5 lb)

Large-grain smooth river pebbles (8–12mm) in natural grey, cream, and charcoal tones that create a rugged stream-bed aesthetic. Well-suited to goldfish tanks, koi aquariums, and hillstream loach setups where a sturdy, gap-rich substrate is needed. The coarse size promotes strong water circulation through the substrate bed and is easy to vacuum without disturbing the layout.
