Benefits of using CO2 regulator in fish tank
1. Healthy plant life
A well-known fact is that plant life and fish need to exist together in balance. The plants flourish on the carbon dioxide (CO2) that is filtered out by the fish. In return, the fish feast upon plant matter and also seek shelter underneath the plant. However, too little or too much CO2 level will affect both fish and plants.
Side effects of the absence of carbon dioxide include plants that have stunted growth or pale stems and leaves. This likewise implies that the plants won’t be able to provide the right supplements to the fish nor correctly aerate the environment. Such negative circumstances are best prevented by the installation of a good CO2 system or regulator.
2. Healthy fish
Carbon dioxide plays an indispensable part in the life of fish and other aquatic habitats. Too little or too small may harm your fish and possibly lead to their untimely death. Fish filter out carbon dioxide when breathing. An excessive level of carbon dioxide in the water increases the toxic level, thereby affecting the PH balance. However, unless you are exceptionally skilled in noticing or detecting the level of CO2, what you are likely going to see is dead or sickly fish. A CO2 system helps in putting the CO2 at a moderate level thus reducing the negative impacts.
3. Combating algae growth
Algae is indeed one of the greatest threats to fish. It affects the life of fish by producing an unhealthy condition that can cause infection on the fish and other plant life. Studies prove that CO2 contributes to algae growth and likewise leads to abundance ammonia which is risky for fish. Installing a CO2 regulator in the aquarium for monitoring the level of carbon dioxide helps battle the negative impact.
Truly, it might look quite easy, however, the value of a decent CO2 regulator is clear. It enhances the quality of water, boosts the wellbeing of both plants and fish, and likewise keep the growth of algae and other related control under control. Nonetheless, you need to know that all CO2 systems aren’t the same. This is why you need to buy quality CO2 systems and regulator from reputable dealers.

How to choose the best CO2 regulator aquarium
We will now show you what we believe to be the main features to consider when looking for the best CO2 regulator aquarium. Discussed below are some of the features to consider:
Generally, installing a CO2 regulator is quite simple. It tends to be as easy as connecting a couple of tubes and turning a couple of knobs. However, you may want to spend some hours adjusting and twisting the knobs to get the ideal amount of CO2. It is good to know that even the best CO2 system will need some good finger work. However, you won’t want to go extreme with this.
This is talking about how easy you are able to read the gauges. If you know that your eyesight isn’t as good as it was before, we suggest that you go for a CO2 regulator with a gauge that is quite easy to read.
3. Is the system dual stage?
In case you are a newbie when it comes to CO2 regulators, it is better to know about this factor. The dual-stage CO2 system is two regulators made into one. The primary stage thumps the pressure down to a consistent PSI for the second one.
This prevents variations because of changing PSI in the aquarium. Both stages will provide extra protection. To say the truth, single-stage CO2 regulators are more affordable and are often used without any issues. Nonetheless, it can be risky and can be quite difficult to obtain a consistent and reliable output.
This will depend solely on your circumstance. If you are going to use your CO2 system for different tanks, you will need to get one that very compatible with the CO2 cylinders (5lb). Or on the other hand, you will be replacing your regulator always.
Then again, if you find it difficult to get the CO2 cylinders or you simply need it for a single tank. You might need to search for one that is highly compatible with the normal paintball cylinders (24oz). These, incidentally, are quite easy to acquire.
Top notch materials mean that it will last for a long time. And most people would prefer not to put resources into a gear that can easily break. Brass and stainless steel are your best choices.
Some of the kits discussed below are more of a bonus package and some are absolute necessities. We will let you know which kits as we discuss each of them.
- Needle valve
This is also known as a pressure relief valve. If you need a quality and safe CO2 regulator, this kit is very important. It gives you exact control over the measure of carbon dioxide entering your fish tank. Needle valves enable you to exquisitely tune and control the rate of flow (i.e. the CO2 bubbles at each second) at your preferred level. It is essential to buy a top-notch pressure relief valve since it enables you to stay away from the scary dumps at the base of the tank.
- Bubble counter
The bubble counter is a visual apparatus, making it simple for you to gauge the quantity of bubbles entering your aquarium at every second. This kit is not a deal-breaker, as most CO2 regulators do exclude one. Yet, we would suggest that acquire one as it enables you to make exquisite adjustments to the rate of flow.
- Solenoid valve
Solenoid valves save you some money by preventing the wastage of CO2 amid the “lights-off” periods when your plants are no longer in need of carbon dioxide because they enable you to put the regulator on a programmed timer. It is much better if the CO2 system comes with a light indicator a to let you know whether it is on or off. So, you can just manually turn off the supply of carbon dioxide on a CO2 system without one. But in many homes, there is not always people around at the appropriate time to do this and that where the solenoid valve comes in to provide aid.
A good CO2 regulator must come with two gauges i.e. one for low pressure and the other for high pressure. The gauge for high pressure must read no less than 1000 PSI as majority of CO2 aquariums comes with 800 PSI. The gauge with low pressure should read no less than 15 to 30 PSI and a maximum estimate of 200 psi. Note, a CO2 regulator with dual gauge doesn’t mean that it is a dual stage.
- Check valve
If the check valve is excluded in the CO2 regulator kit, then you will need to get one. This is a vital safety feature, safeguarding against a reverse-flow of aquarium water into your CO2 system. At the point when your CO2 breaks down in water, it enters into the tubing again once the infusion of CO2 has ceased. If you do not don’t own a check-valve kit, the water could get to your CO2 system and destroy it.
- The washers
This may appear to be little. However, if the washers come with an irregular size, it can be a big issue trying to discover replacements. Washers of regular sizes are standard and very simple to find.
What is the best CO2 regulator for aquarium
All the brands of CO2 regulator that we have reviewed so far aren’t really different from one another. They are all built with brass, they have almost the same PSI grading and they all come with a similar solenoid valve pattern. The final choice truly comes down to personal preference and budget.

How to use CO2 regulator aquarium
After purchasing your CO2 regulator and all the equipment needed for its installation, you can assemble them by following this guideline.
Step one: Attach your CO2 system to the cartridge. You don’t need to stress yourself, most CO2 regulators are made to exquisitely fit with the cartridges available today and you don’t need to purchase any connector to link them. At some point, a paintball connector will provide some aid.
Step two: Using suitable CO2 carrier tubing to link the air outlet directly from the CO2 system with a check valve and afterward with a diffuser. In case your CO2 isn’t properly designed with a bubble counter, then you need to get one and interface it with the air outlet directly from the system. The diffuser is usually positioned at the rear end of the regulator where CO2 is transformed into good-looking bubbles which are then infused in the water inside the tank.
Step three: Positioning the diffuser in the right place in your fish tank, where there is constant circulation of water, by utilizing suction containers.
Step four: Assemble a drop checker for CO2 and then place it in the fish tank with a suction container. This gear helps to detect the exact concentration of CO2 in your planted aquarium. By adjusting the CO2 system with the use of a drop checker, it is possible for you to get an optimum concentration of CO2 in your planted aquarium. The recommended CO2 level for a planted aquarium is roughly 26 to 35 PPM.
