How to Select an Air Stone?

When searching for the perfect air stone the most important thing needed to be taken into account is the size of the aquarium. The stone is meant to put out needed oxygen into the water and create a flow to have the fish happy and healthy.

The main reason for buying an air stone is to produce the proper amounts of oxygen into the tank. Some air stones offer an option to lower the CO2 levels as well. This might be a better option when searching for an air stone for a larger aquarium due to the large levels of water and fish.

A smaller air stone is better for a smaller aquarium. Making sure to not over power a small aquarium is of importance, so the fish can still be comfortable in the environment. A bigger air stone is needed for a larger aquarium so the oxygen flow into the aquarium is sustainable for the fish to survive.

Visual effects are also something to consider when picking out an air stone. There are air stones that come with LED lights for better visual effects. While other air stones simply produce a small wall of bubbles that do not offer any visual effects.

Air tubing is a simple product and most air stones have a standard sizing. Most air stones do not come with the needed tubing, so this is a must purchase. The length of the tube needs to be long enough to fully reach the air pump and the air stone while submerged. Most air tubing comes longer and can be cut to length if a shorter length is desired.

Once the tubing and pump is purchased the air stone can be set up for the aquarium. The air tubing will connect to an output on the air pump and connect to the air stone. Once the pump is plugged in and working the pump will produce an air output. This will travel to the air stone through the tubing and produce the bubble wall that is desired from the air stone.
