And because it runs on DC power sources, it is also very simple to plug it into a different socket in case there is a power cut.
Plus, it comes with a bubble counter, making it very simple to understand how much CO2 is flowing into your aquarium. This way, you can moderate it according to the size of the aquarium.

Moreover, just like the previous item, this also comes with a bubble counter and a check valve.

Also, this device would not annoy you or your house guests with the constant annoying buzz that is common to most CO2 systems.
What Could’ve Been Better?
After using the device for a few weeks, we encountered a strange problem. The cable of the device was pretty weak and got twisted and came off.

Aquarium CO2 System Buyer’s Guide
Now that we have discussed the top 5 aquarium CO2 systems, we hope that you have a more clear idea in your head about their features and functions.
However, we have to say that you are only halfway into your destination of choosing the best CO2 system. In order to do that, you have to take a few other things into consideration too. These factors are very crucial in determining how well your CO2 systems would function.
In this section, we will discuss some of those factors. Let’s check them out.
-
The Price
Aquarists sometimes face a dilemma about how to choose the most efficient but economical option when it comes to CO2 systems.
Let us tell you that it does not always necessarily mean that economic ones do not perform well. Quite contradictory, if you research a little and learn the ways to create your very own DIY CO2 system, it can be a very effective option.
There are very good kits that are available on the market and allow you to set up the entire system based on your requirements. You will get all the tools and devices necessary to set it up available in these kits. And it is quite economical too.
However, if you do not want the hassle and also save time, you can go for options that come pre-assembled. But, keep in mind, they are generally a little more costly.
-
Regulator
Not every aquarium is of the same size, and thus they need different CO2 levels to maintain the healthy life of the plants and fishes.
But then again, all systems are attached to the tanks. So, how do you control the level of CO2 released? Well, you guessed it right: through the regulator!
The regulator helps you to decide the tank’s pressure. But what you need to ensure is that it is easy to control the regulator. Not just the control, it should also be easy to read. If the font size is too small, or if the writings are blurry, you will have a hard time noting the reading.
However, make sure that the gauge and regulator are not too big, as that would ruin the beauty of your aquarium. And lastly, before you decide on buying a kit, do check if the regulator comes with a needle valve.
This is what lets you moderate the level of CO2. In case it is not included in the kit, you will have to buy it separately.
Verdict
That’s all for today, folks!
We hope that you had as much fun going through this comprehensive guide as we had while experimenting and writing about the products. After reading this, we hope that you can make a more informed decision.
But, before saying our goodbyes, we would like to let you in on our favorites. Fluval Mini Pressurized CO2 Kit has managed to stand the test of time and is the best overall.
If you are looking for a pocket-friendly option, then FZONE Aquarium CO2 Regulator DC Solenoid is the best bet. And if great customer service is your prime concern, then Decdeal Aquarium DIY CO2 Generator System Kit is an excellent consideration.
And with that, it’s a wrap. Until next time, take care!
