CO2 plays a vital role in the life of fish. Too much or too little will not only harm the fish but may lead to the untimely death. Fish produce carbon dioxide during respiration. Too much CO2 in the water increases toxicity and affects the pH balance.
What does CO2 do for fish tank?
CO2 is arguably the most important element in the planted aquarium. It is required for respiration and growth by all aquatic plants, used in a process called photosynthesis.
Can too much CO2 hurt fish?
Yes, if your aquarium has too much CO2 i.e. CO2 levels more than 30 PPM then it is toxic for your fish. This is because if your aquarium has too much CO2 it reduces the ability of fish to take oxygen in and your fish will struggle to get oxygen. This will suffocate the fish and it can even cause death.
Is CO2 booster safe for fish?
API CO2 BOOSTER Freshwater Aquarium Plant Treatment is safe for use with freshwater fish and will not alter pH levels in aquariums. Use with API LEAF ZONE and API ROOT TABS Plant Fertilizer for complete plant care.
Do aquariums need CO2?
Carbon dioxide isn’t required, unless you have about 3 or more wpg. … Besides light and carbon dioxide, aquatic plants need a variety of other nutrients. Basically, in an aquarium with low to moderate lighting, the fish food you put in the planted aquarium can probably provide enough of the macronutrients.
Will adding CO2 reduce algae?
Overall, adding CO2 or increasing CO2 in the aquarium can help to reduce algae in your aquarium if you’re providing too much light to your aquarium plants.
Does CO2 lower pH in aquarium?

Should I turn off CO2 at night?
Why do I need to switch off at night? At night plants don’t use CO2, they produce it. … The levels of CO2 in the water could also reach toxic levels, resulting in a tank of suffocating fish by morning. Most experts recommend investing in a regulator with a night shut-off valve to turn the gas off overnight.
Does CO2 increase pH in aquarium?
As we add CO2 to water, it forms carbonic acid, which lowers the pH. The more CO2 that gets dissolved into the water, the lower the pH.
How much CO2 should I put in my aquarium?
Dennerle recommends a CO2 concentration in the aquarium of between 15 and 30 mg/litre – a value between 20 and 25 mg/litre is ideal. The dosage required for this CO2 concentration depends on various factors such as planting, water flow, surface/volume ratio etc.
Is liquid CO2 bad for fish?
CO2 is toxic if overdosed. Some fish are more sensitive than others, especially if oxygen levels are low, such as at night where plants respire taking in oxygen and producing CO2.
Is liquid carbon bad for fish?
