The Marina rectangular air stone is a perfect choice for enhancing any aquarium. It diffuses air effectively, generating gentle water movement. This not only adds visual interest but also increases surface agitation, speeding up oxygen replenishment and helping to release built - up carbon dioxide. Simply attach the air stone to your airline tubing and position it wherever you like in the tank. It comes in three convenient sizes: 10 cm (4 in) diameter, 15 cm (6 in) diameter, and 30.5 cm (12 in) diameter.


Using your Marina air stone is a breeze. First, connect it to your airline tubing. Then, place it in the spot you want in the aquarium to create that cool water movement. When choosing a size, think about the size of your tank - smaller stones work well for small aquariums and bigger ones for larger tanks. As for maintenance, give it a gentle clean every few weeks. You can soak it in a mild aquarium - safe cleaner and then rinse it thoroughly. Avoid using harsh chemicals as they can damage the air stone. Also, make sure the airline tubing is always in good condition to keep the air flowing smoothly.
