Dual Gauge CO2 Regulator
There are two basic requirements for plants to grow through photosynthesis; nutrients and light. The most important nutrient for plant growth is carbon. Since carbon dioxide (CO2) is abundant in the atmosphere, plants simply draw their carbon directly from CO2 in order to photosynthesize and grow. In an aquarium, CO2 levels are naturally very low and without any supplementation, submerged aquatic plants will not be able to grow properly. When CO2 is a limiting factor, plants cannot fully utilize all the available light to photosynthesize. This can allow algae to grow and compete with the plants for nutrients, further stunting plant growth. By introducing CO2 into the aquarium, plants can achieve healthy growth faster and therefore outcompete algae.
The introduction of carbon into an aquarium is typically achieved by using a pressurized gas tank controlled by a regulator, solenoid and needle valve. Pressurized CO2 is the best way to go for the more advanced hobbyists or for those keeping larger aquariums, 20 gallons or above.
The CO2 regulator is one of the most important aspects of any CO2 system. The pressure in a gas cydlinder can be over 700 psi which is way too high for safe usage in any application. The regulator plays the crucial role of allowing just enough CO2 to dispense safely through the airline tubing, through the diffuser and into your aquarium.
The UNS Dual Gauge CO2 Regulator contains two gauges to show both working pressure and gas pressure in your tank
Works comfortably with Advanced Precision CO2 Brass Bubble Counter
- Adjustable working pressure up to 5 Bar/ 70 PSI
- CGA320 thread connection stem adapter included (fits onto standard US CO2 gas tanks)
- Precision SMC Needle Valve with built in locking mechanism for precise CO2 metering
- Built in solenoid allows you to turn the CO2 supply on and off during photoperiod
- Fits disposable CO2 cartridges
- Adjustable knob allows the ability to adjust working pressure
What else do you need to get to supply CO2 to your aquarium?
Output pressure gauge: 0-160 PSI
Tank/high pressure gauge: 0-4000 PSI
Pressure Relief Valve: 100 PSI
