When to Turn Off CO2 in Aquariums

CO2 is necessary for plant photosynthesis, but it can also be toxic for fish, snails, and shrimp. Here are some ways to keep it in balance in your aquarium. Using a bubble counter is a great way to test for CO2 levels. Just remember that plants do best at 30 ppm of CO2 underwater. If your plants aren't growing well, you may not be giving them enough CO2.

CO2 is essential for plant photosynthesis

CO2 is one of the most important elements in a planted aquarium. This is because plants need CO2 for respiration and growth. This gas also serves as the source of energy for photosynthesis. During the day, plants need a constant supply of CO2 to conduct photosynthesis. They do this by combining carbon dioxide with water and light energy.

Natural environments for plant growth typically have high concentrations of CO2, including carbon dioxide derived from the decay of organic matter and underground storage. Although the levels of CO2 in ground water are usually constrained due to off-gassing, virtually all spring water is high in CO2. CO2 levels at the head of a spring are usually high, and decrease as the distance from the headwater grows. This is why many of the aquatic plant species in aquariums originate from springs. The CO2 levels in a standard aquarium are a couple of parts per million.

Although plants do not show symptoms of low CO2 levels immediately, if the levels are low enough, they will be stunted or die. These symptoms are often accompanied by algae growth and poor coloration.

It is toxic to fish

CO2 can be dangerous for fish, depending on the amount present in the water. Too much of it can upset the water chemistry and lower the pH. It is also toxic to fish when it reaches dangerous levels. Some fish biologists recommend keeping the CO2 levels below 10 ppm.

Using a gas injection system to add CO2 to your aquarium is a popular method. While the increased CO2 level benefits the plant life in the aquarium, CO2 can be detrimental to fish and other invertebrates. This is why it is important to monitor the level of CO2 regularly.

It is toxic to shrimp

High CO2 levels can be harmful to shrimp. High CO2 levels can cause hyperventilation in shrimp, which will ultimately kill them. This is due to the fact that the solubility of CO2 in water is much higher than that of O2. This toxicity causes the shrimp to unable to expel CO2 from their bodies, which leads to a staggered swimming style and eventually death.

Excess CO2 is very bad for all aquarium inhabitants. It's also harmful to plants in the tank. Plants are composed of carbon, and they absorb CO2 from the air to help grow. Excess CO2 in the aquarium is not only bad for shrimp, but also for the plants in the tank. Luckily, CO2 levels in aquariums can be controlled.

It is toxic to snails

Many people are unaware that the Co2 found in aquariums is toxic to snails. While this is true to a certain extent, it is generally a minor concern for snails. If you are worried that your snails are suffering from this toxicity, you should contact an aquatic specialist. They will be able to answer your questions and provide you with recommendations on snail care.

If you want turn on/off the co2 automatically, you could choose a solenoid bubble counter, connect the solenoid bubble counter with a timer, you could set the working time, and control the co2 supply automatically, keep your aquarium tank co2 level with normal. Avoid your fish, shrimp and snails die as lack of air.

Meantime, if you have enough budget, a co2 drop checker suggest to buy, which could help you read the co2 level in tank correctly. If the color shows blue means lack of co2, green means ok, yellow means too much.
