Frequently asked questions

Do air pumps add CO2 to water?

Yes, air pumps pump fresh air to water. This means they pump all gas in the air including N2, O2, CO2,… to the water, not only O2. We all know oxygen is needed for the good health of plants and fish in an aquarium. Having said that, CO2 is also vital for life in aquatic systems. They help in photosynthesis for aquatic plant life.

Can air pumps replace CO2 supplies in aquariums?

While air pumps do help to increase CO2 in aquarium water systems, this might not be enough. It all depends on the density of plants you have in your tank. If you do not have too many aquatic plants that use up CO2 produced by fish, then an air pump is enough for your tank. This is not true if you have more plants. Additional CO2 supplies might be needed.

Are fish okay with excess air bubbles?

Air pumps agitate the water surface to facilitate better gas exchange, producing lots of air bubbles. Air stones in aquariums also help to produce bubbles. This is considered good for aeration and for fish to play in. However, some species of fish can get stressed with too many bubbles. It is recommended to choose an air pump with moderate power to suit the kind of fish in your tank.

Is it normal for Bettas to come up for air?

Bettas do tend to come up to the surface at times. Keen aquarists would have noticed this trend. However, if this is happening too frequently and your Bettas are seen to be gasping for air, there could be lack of oxygen in your tank. It is wise to check for levels of oxygen in your fish tank at this point.

Bottom line

An efficient air pumping system is essential for good water quality in aquariums. Optimum air bubbles can help to provide good aeration in your tank. Choose your air pump from the given options depending upon the size of your aquarium as well as the type of plants and fish that you will have.
