Are air bubbles in my aquarium really necessary?
This is a great question. Having 25 years experience in the hobby it took a long time for someone to answer this. So, after having every type of aquarium available, from fresh water to salt water to reef, I have come up with my own answers.
First of all It has been my experience that aeration can only benefit your aquarium ecosystem. The fact that bubbles look good in the aquarium, although true, is not enough. Bubbles have to dissolve in the water in order to give your fish the most available oxygen to breathe. This can be accomplished with an air pump, tubing, and a good airstone.
Secondly, the air stone should put out as many bubbles as possible and as fine as possible. Now I have seen starter tanks with sea chests and pirates in them and they may look great, but the truth is they are just decoration and the bubbles are too big to be helping your fish. This sand airstone makes a good fine bubble flow and is reasonably priced. The idea is to have a gentle flow, that doesn’t create a tidal wave on top of the water but barely breaks the surface of the aquarium. Couple this Air stone with a check valve, that will stop water from flowing back into the pump, and a good air pump and you are all set.
Lastly, and most important, the airflow in the water will increase oxygen and help prohibit certain types of algae growth. Correctly aerated water will increase fish appetite and make fish more active. All benefits for your aquarium inhabitants.
Yes, aeration is necessary for fish health. For minimal, cost you can make your aquarium healthier and improve water quality. Enjoy the hobby and let’s keep all the inhabitants at their best.
