The Crystal Bubbles Aquarium Aeration Stones are a set of 12 gray air stones that are widely applicable for freshwater, saltwater/reef aquariums, and hydroponic use.
They are designed to increase oxygen levels, "blow off" CO 2, and raise pH, and can be easily driven by even nano air pumps.
Made of durable and sturdy material, they are safe for your fish. The stones measure 0.80" in diameter x 2.00" H and fit standard airline tubing aquarium and CO 2 tubing with an inner diameter of 3/16" (4mm).
Note that they have to be soaked in water for about 30 minutes before connecting to an air pump to run.
