What is a C02 regulator?

The main component in any aquarium containing plants, should be a quality CO2 regulator setup. It is used to control and maintain the health of all amphibian plants. The regulator contributes massively to the development of every single plant through assisting in photosynthesis. Quality lights and CO2 regulators should be at the top of your list when building your dream aquarium. For the plant life in your tank to survive, it needs a steady supply of CO2 during daylight hours. Specifications of these CO2 regulators depend on make and model but all of them attempt to accomplish the same thing. Aquarian plants utilize asteady stock of CO2 along with light to provide oxygen and certain sugars, which in turn assist their development.

Maintaining an Eco-system is a delicate task. We are trying to replicate perfect conditions for all life in our tank to thrive. In nature plants are usually subjected to vast amounts of C02 through natural processes. In a closed environment we need to attempt to re-create these conditions. In a closed environment such as an aquarium, CO2 is naturally restricted. Water that we artificially place in an aquarium has a restricted CO2 content, and there are no natural processes to provide it naturally. This is why it is recommended to enhance your tanks CO2 content through a regulator. This will replace these natural processes and ensure that your Eco-system has is more grounded.

Light and CO2 production go hand in hand. So the amount of CO2 that is needed is generally dependent on the lighting systems you have in place, or wish to install. Furthermore, the type of plants that you have will also require a certain consideration.

Bubble Counter

How can we monitor C02 visually? The amount of CO2 in your tank is paramount to it's health. A bubble counter gives the aquarist a visual method of determining CO2 levels entering the aquarium. Generally you will find these added to any CO2 regulator systems due to it's user friendly nature. A bubble counter is used to adjust your regulators. You can count the amount of bubbles per second and calculate the CO2 entering the aquarium.

Output Pressure

Output pressure is the measure of dispensed CO2 that is being let into the tank. These systems are created with safety systems in place. CO2 outlets should always be compatible and accordingly rated. Gauges or systems with dual gauge features are commonly seen to appropriately regulate pressure. From a dual stage regulator to systems that maintain easy installation, the sky is the limit.

Generally the output pressure is regulated to reduces the pressure that is found inside the cylinder to appropriate levels. A pressure reducing regulator will produce a controlled and reduced pressure output, inline with what you require.
