AquaHolland CO2 pressure regulator - very fine adjustable needle valve

CO2 is an important, if not the most important, nutrient in the aquarium. Just like the trees in the wild, your aquarium plants need CO2 to do photosynthesis. If you dream of an aquarium full of beautiful aquarium plants, then it is best to invest in a good CO2 system.

Unfortunately, a well-equipped CO2 system is not the only condition for good plant growth, you must also be able to adjust your CO2 optimally. Too little CO2 leads to poor growth of your plants and consequently algae growth, but too much CO2 can be harmful to your fish.

Plants are dependent on CO2 for their photo synthesis. A densely planted aquarium will therefore have a much greater need for CO2 than an aquarium that is planted only thinly. It should also be taken into account that fast-growing plants use more CO2 than slow-growing plants.

The most important part of the CO2 device is the pressure regulator and the needle valve. The pressure reducer is used to reduce the pressure from the CO2 bottle to the desired level, in most cases 1.5 bar. With the needle valve you control the amount of CO2 that is injected into the aquarium. The injection rate is usually measured in bubbles per second.

The AquaHolland CO2 pressure regulator is equipped with 2 Wika pressure gauges (0-4 bar and 0-250bar) for an accurate reading and a needle valve for fine adjustment of the amount of CO2.

The connection fits on the most common gas bottles.
