Outflow stones and backflow preventers so that the air in the aquarium ends up where it needs to be

Oxygen dissolves in water at the interfaces, i.e. at the surface of the gas bubbles. If you want as much oxygen as possible to dissolve in the water, you have to increase this surface area, which is done by making the bubbles smaller. Outlets can do this. To prevent water from creeping back in the hose and destroying the air pump, a backflow preventer or check valve is installed as a backflow protection.

In the aquarium, depending on the setup, an air supply can be very useful. At higher water temperatures the capacity of the water to absorb oxygen decreases - especially in summer this is a circumstance that can cause problems. The higher water movement causes more CO2 to outgas, and the air bubbles allow more oxygen to dissolve in the water.

Additional aeration of the aquarium water at night is also useful, especially in heavily planted tanks. The plants breathe oxygen at night, so they consume oxygen just as much as the aquarium fish, dwarf shrimp, snails, crayfish and other stock. An outflow stone or a basswood diffuser, connected by an air hose to an air pump located outside the aquarium, can remedy this situation and prevent a lack of oxygen, which would be fatal for the aquarium animals.

A backflow preventer is also called a check valve or backflow preventer. This valve is installed in the air hoses on the aquarium to prevent water from creeping back in the hose and causing damage to the air pump - as is well known, electrical appliances and water are not a particularly good combination ... For this purpose, the backflow preventer or check valve is only open in one direction. The direction of air flow is indicated by an arrow. Be sure to install the check valve the right way around to avoid damage to the pump.

The air bubbles that come out of an air pump are very large and rise to the top of the aquarium water relatively unchanged. The oxygen dissolves in the water only at the surface of the bubbles. Many small bubbles have a much larger surface area than one large bubble, so even in the aquarium you look to break up the incoming air as finely as possible. Also, many small bubbles make less "storm" in the aquarium than a few large bubbles that rise quickly. The fine bubbles bubble upward, which not only makes sense, but also looks really nice. Plus, fine bubbles are virtually silent, which is more than you can say for giant bubbles bubbling upward.

Here in the Garnelio online store you will find outflow stones in the proven quality of JBL. They are made of quartz sand mixture and are available in different sizes - suitable for your aquarium size. In addition, you can buy outflowers made of the naturally fine-pored lime wood also in different sizes.

An air curtain is a nice alternative to outflow stones. This is a perforated air hose that is laid in the aquarium and which releases a whole series of fine air bubbles - a beautiful detail for the back wall in the aquarium, for example.
