How CO2 Diffusers Function in Fish Tanks

 

There's no denying the fact that carbon dioxide plays an important role in your aquarium. Equally vital is the need to have balanced levels of it. If you inject too much or too few, you can only watch in agony as all your plants and fish perish. If you hit that sweet spot, though, then you can marvel any time you want as your fish and plants thrive, glow and flourish in their small, yet exquisite aquatic world.






The difficulty in the supplementation of carbon dioxide on aquariums with live plants is that such plants also release the said gas at certain times of the day. If this is left unchecked, this could cause a carbon dioxide buildup, which could threaten the oxygen levels of the tank, thereby leading to the death of the fish, besides disturbing the aquarium’s pH balance. Another issue is that certain live plants won’t survive in an aquarium without higher than normal carbon dioxide levels. After all, the three main factors that you should always be mindful of if you want your aquarium plants to grow and thrive properly are nutrients, lighting, and, of course, carbon dioxide distribution. 

 

What will a CO2 Diffuser Do for My Fish Tank?

 

This is where a CO2 diffuser comes in. These diffusers are basically the ones that are responsible for helping carbon dioxide dissolve better in aquariums. After all, if you directly inject carbon dioxide into water, chances are they will only form as bubbles and not readily and optimally mix with the water. 

 

Depending on the diffuser that you are using, this nifty implement usually does this by interacting with the water and make it possible for it to easily absorb carbon dioxide, which makes it possible for the said gas to linger in the water for extended durations. The process by which diffusers interact with the water is called agitation, which simply put, is the act of mixing carbon dioxide with the water in the aquarium.

 

The most efficient types of diffusers are usually the ones that come in spiral shapes, also known as baffle systems. They are designed as such in order to delay the injection of carbon dioxide into the fish tank, making it easier to regulate. There are also bell-shaped diffusers that keep the carbon dioxide in their bell-shaped structures in order make sure that the gas is being diffused in the best way possible. There is also a special type of CO2 diffuser that is utilized to lower the water’s pH levels as well. These are usually installed if there are corals in the aquarium that need calcium injections as well. 

 

Of course, these are all done based on the suggested carbon dioxide injections that your aquarium needs. And, based on the facts stated above, no two aquariums have the same carbon dioxide requirements. This is why it’s best to consult experts first regarding this very important specification. A lot of aquarium owners make this common mistake, which results in the noticeable stunted growth of the plants and, if it’s not addressed, could even lead to their death.
