Best CO2 Diffuser For Aquarium

Thanks for sharing!

Identifying the Best Co2 Diffuser For Aquarium that will give the appropriate solutions and remarkably handle the affairs of the water in the tank is very important for you.

CO2 plays an indispensable role to the photosynthesis of aquatic plants, but the aquarium can not provide a genuine environment for plants’ growing, so it becomes important to add adequate amount of CO2 to the aquarium.

One of the common concerns among hobbyists just getting started with high tech setups is achieving adequate co2 without causing harm or stress to their fish.

As a general guideline, most aquarists can agree that 30ppm of dissolved co2 is necessary for the plants and fish to thrive.

But how do we know if we have too much or too little?

A glass drop checker with a standard solution is by far the most reliable way to have a visual representation of your co2 levels without all the guesswork. It is also the most straight forward.

The diffuser helps to effectively dissolve CO2 into your aquarium, while the CO2 Bubble Counter provides accurate monitoring of the CO2 dosing.

Beyond doubt, obtaining adequate amount of carbon dioxide into a planted fish tank could be intricate. Indeed, this is one of the reasons why opting for the best CO2 diffuser for aquarium is deemed as quite indispensable for your live aquatic plants to shoot up inside the tank.

These products are especially built to be capable of adding the appropriate amount of CO2 instantly and without any hassle. The good news is that they are relatively less pricey and no sweat to set up in the tank.

It is noteworthy that freshwater fish tank plants take in CO2 and dispense O2 into the tank water. Hence, they require more CO2 to bloom as compared to what is already derivable from most freshwater fish tanks. And, this is where a carbon diffuser makes a very vital device for most aquarium owners to invest in.

Luckily, there are a considerable number of carbon dioxide diffuser options to select from on the market nowadays; however, you cannot just simply get one of these without much insight of the necessary features that you need to look through.

Can I count the bubbles? Should I buy a bubble counter?

A bubble counter is a vital technical component in the carbon dioxide supply of live aquarium plants through carbon dioxide system. It is described as a tiny receptacle that is filled with water.

To put simply, you can easily monitor the amount of carbon dioxide being entered into the fish tank with the aid of a bubble counter.

It is interesting to note that the bubble counter works by transmitting the carbon dioxide through a liquid in order for fish tank owners to easily and accurately count the bubbles in the system.

In addition, the number of bubbles is generally gauged at the specific time unit and this aims to provide the aquarium keeper a specific value to compute with, allowing him to keep track of the carbon dioxide amount being introduced in the fish tank so he could possibly make some correlations with the recommendations.

What is a CO2 Diffuser and What is its Purpose?

Freshwater aquarium plants absorb carbon dioxide and release oxygen into the water. That said, they need more carbon dioxide to thrive than what is readily available in most freshwater aquariums. That’s where a CO2 diffuser comes in.

Because CO2 is a gas, it takes a little work to dissolve it into the water. Simply bubbling it through won’t provide the levels that plant life needs to thrive. Diffusers work in part by increasing the surface area of water exposed to the gas.

This is usually accomplished by feeding CO2 through a ceramic disc. This both agitates the water and keeps it in contact with the CO2 for longer periods of time, allowing it to be more effectively absorbed.

Best CO2 Diffuser for Aquarium

There are plenty of CO2 diffusers to choose from. While they all accomplish the same thing, there are various ways to go about it. Most are made of glass, some of stainless steel. They come in different sizes and shapes, too.

Best Place to Put a CO2 Diffuser in Aquarium

There are a few things to think about when it comes to placing a CO2 diffuser to get optimal results.

First, it should sit close to the bottom of the tank. The more time the bubbles spend in contact with the water, the more it will be absorbed. You might be tempted to place it under the substrate, but this isn’t ideal. Why?

Because the if the surface of the ceramic disc that releases the bubbles is blocked in any way, the bubbles won’t keep their small size. They collect and gather into larger bubble, which doesn’t absorb as effectively.

You should also avoid placing it among plants. While it may seem that this would be a good place for it since it’s for the benefit of the plants in the first place, it can cause some problems.

For one, you’ll run into the same problem as with the substrate, meaning the bubbles will collect on the plants and combine into larger bubbles.

Remember, the goal is to circulate the CO2 bubbles as much as possible, giving them as much time as you can to absorb. One good place to position it is under the filter return.

That way, the water coming back into the tank will push the bubbles back down which is one way to keep them circulating longer.

If you’re unable to position your diffuser that close to your filter, try to put it in a place where the bubbles will get caught in the current created by the filter return. Again, this will keep the bubbles circulating and prevent them from surfacing too quickly.

One more thing to remember is that you might have to move the diffuser as the plant life begins to grow. When plants get taller and denser, the flow of the water will be affected and you can run into the same problems we mentioned earlier, bubbles collecting and becoming too large then quickly escaping to the surface.

How to Install a CO2 Diffuser?

Installation will be slightly different depending on the model you’re installing but here are the basics.

First, you’ll need a CO2 tank. It’s also highly recommended that you use a bubble counter. Fill the bubble counter tube ⅓ of the way with freshwater keeping the open end of the tubing submerged so it doesn’t suck in air. Make sure the O-ring is secure so there aren’t any leaks.

Mount the bubble counter to the side of the tank or wall so it’s easily visible. Then, cut tubing to connect the CO2 tank to the bubble counter. Leave a little bit of slack, you don’t want this fitting to be taut.

Next, connect the bubble counter to the CO2 diffuser with another length of tubing. Make sure you use enough tubing. Again, you don’t want it to be taut and you want to have enough length so you can make sure the positioning is correct. After they’re connected, place the diffuser into the tank.

Keep in mind that plants only absorb CO2 through photosynthesis so they’ll need sunlight or another light source. When it’s dark, they actually release CO2 so the diffuser shouldn’t be running if the light is turned off.

What are the different types of aquarium CO2 diffusers?

  • CO2 Reactor

This is popular for being one of the most costly types of diffusers and is capable of providing the highest output of carbon dioxide. Such unit is highly practical for use for fish tanks that come in bigger sizes.

  • Ceramic Glass CO2 Diffuser

This is generally immersed into the aquarium and is safely secured to the fish tank glass with the aid of a sturdy suction cap. What’s more, this produces light and tiny bubbles and is sold at a much affordable price tag.

  • In-line CO2 Diffuser

This is commonly attached to the fluvial canister filter and it is useful for fish tanks that contain large amount or more gallons of water. Such unit is highly recognized for being quite efficient and safe to utilize. You could save more on carbon dioxide consumption mainly because the carbon dioxide that enters the water has significant amount of time to disintegrate.

  • Airstone Diffuser

This type of diffuser is not highly recommended. For a fact, it is only a waste of money to invest in. It produces large carbon dioxide bubbles and this makes it difficult for carbon dioxide to be dissolved into the fish tank.

  • Ladder CO2 Diffuser

This one is specifically built for fish tanks that come in smaller sizes. It works efficiently and you can get it at a very pocket-friendly price tag. Its name was actually derived from its ladder-like shape

 

Conclusion

All types of aquatic plants need to be provided with adequate amount of oxygen as well as carbon dioxide in order for them to stay alive, vibrantly colorful and fresher inside the fish tank.

And, to achieve this, the best CO2 diffuser for aquarium can help you ease the job of maintaining the safety and good health of your live aquarium plants.

Assuredly, by using the appropriate unit for your fish tank, your most valued plants will have all the things they specifically necessitate to keep flourishing, and thus, give you the happiness and satisfaction in viewing a nice-to-behold aquarium inside your dwelling place.

For freshwater plants to thrive, most aquariums need additional CO2. The only way to add it effectively is with a CO2 diffuser. By using the best one for your aquarium, your plants will have everything they need to thrive.
