Many aquarists consider back and forth whether they really need a CO2 system for a nano aquarium. The consideration is from various factors dependent. As is well known, the CO2 system is used to fertilize plants.
Due to the good carbon dioxide supply, the aquarium plants grow particularly quickly and lushly. They are also healthier and more vital.
CO2 system against high algae in the nano tank
Plants are very important, especially for nano aquariums. No nano tank can really do without plants. Many plants that are often planted in nano aquariums need a lot of light. This in turn leads to a high susceptibility to algae.
A CO2 system can be helpful to prevent excessive algae growth. The system helps the pool maintain water quality. The chemical balance is known to be very sensitive in very small tanks because there is less water.
Other good remedies against algae are vegetarian fish that feed on the algae. If many algae-eating fish and snails are in the tank, you can do without a CO2 system.
However, if you keep having problems with algae, the purchase is definitely worth it. The system can also only be operated intermittently when the pool becomes greener and greener in summer. Regular water change are also very helpful.
Stable pH value through CO2 system
Plants are particularly important in a nano aquarium as they ensure that the tank remains in balance and that the fish have enough oxygen get to breathe. Algae in particular are known to consume oxygen.
This can become a real problem in the long run. In addition, the CO2 system can lower pH. The relationship between CO2 and pH is well known. Lowering the pH value usually has a beneficial effect on plant growth.
Many fish benefit from low pH levels. A stable pH value in every tank is also advantageous. The more stable the values in a tank are, the better off the fish and plants are.
Live in many nano aquariums shrimp, since their small size makes them ideal residents of small tanks. Despite this, they are a little demanding in their keeping. You feel at slightly acidic water values particularly well.
CO2 system in the nano aquarium
Advantages:
- less algae
- Plants grow better
- pH drops
- more oxygen in the tank
Purchasing a CO2 system is particularly worthwhile if you have the feeling that the plants in the tank are not growing well. This is a sure sign that the water parameters are not in order. The balance is disturbed.
A CO2 system can help to restore the biological balance. Fertilizing with CO2 stimulates plant growth and lowers the pH value in a short time. This then also benefits the fish.
As the plants grow, so does the algae. The aquarium plants consume the superfluous nutrients, which means that the algae are deprived of their food base. By adding carbon dioxide, the plants can produce oxygen.
Plants in the nano tank
Aquarium plants live permanently in the water. Sometimes they also partially grow out of the water. Then they can get the carbon dioxide out of the air.
If the plants cannot reach the surface, they may experience a lack of carbon dioxide. Then the plants stop growing. The result is a lack of oxygen for the fish. In the worst case, the fish or shrimp can then suffocate.
Do the plants grow without CO2 fertilization?
Plants like Gratiola viscidula get by with little carbon dioxide. If you don’t want to fertilize with CO2, you should use such plants.
CO2 pressure system or organic CO2 for a nano tank?
There are also two different ways of supplying carbon dioxide to the pool for a nano pool. You have the choice between a CO2 pressure system and the BIO-CO2 system. Both systems work on different way.
The CO2 pressure system for nano aquariums
Advantages:
- high pressure
- good performance
- rapid plant growth
Disadvantages:
- higher purchase price than a BIO-CO2 system
A CO2 pressure system works with a gas bottle. The check valve prevents the water from running back into the pressure valve and bottle. The CO2 supply can be adjusted using a regulator.
The C02 systems with a glass bottle ensure a high pressure. through the diffuser the carbon dioxide becomes very effective distributed in the water. At a CO2 system with a night shutdown the supply is interrupted at night.
This makes sense because the plants do not absorb any CO2 in the dark anyway, since they do not carry out photosynthesis. This saves carbon dioxide and the bottle lasts longer.
But such a CO2 system costs more than a BIO-CO2 system. Since the system builds up a lot of pressure, the components must be accordingly safe and high quality be. The gas cylinders can be refilled at a specialist dealer.
BIO CO2 system for nano aquariums
Advantages:
- cheap
- no gas bottles
- own production of biomass
Disadvantages:
- less pressure
- Biomass must be renewed every 4 weeks
Since nano aquariums are very small, a BIO-CO2 system is often sufficient to enough carbon dioxide to win. In contrast to a CO2 system with a gas bottle, the CO2 is obtained from a biomassthat you mix yourself.
The fermentation process produces carbon dioxide, which can be fed into the pool. The biomass is cheap to produce because it consists of water, yeast, sugar and cake glaze consists. These ingredients are readily available in any supermarket.
However, one should make sure that the container tightly closed otherwise the foaming liquid will escape. This causes a lot of dirt. It is also important to ensure that the liquid does not get through the hose into the pool.
One downside is that many diffusers don’t work well on BIO-CO2 systems. The pressure is quite low and swaying. For this reason one should make sure that the Diffuser expressly for BIO-CO2 suitable is.
Conclusion CO2 system for a nano aquarium
A CO2 system is sensible for a nano aquarium if you have problems with algae or fluctuating water values has. A CO2 system ensures lush plant growth and lowers the pH value. As a result, the fish are optimally supplied with oxygen and the values stabilize after a short time.
One CO2 system with a gas bottle ensures that lots of carbon dioxide dissolved in the water because they can build up very high pressure. One BIO CO2 system often sufficient for a nano tank and is cheaper as a system with a gas bottle. However, handling a foaming mass is not always easy.
