Can Fish Die From Lack Of Co2

[Tortea]

Just yes or no please.


Because they take in O2 and pass out CO2, now can there be a problem if you have so many plants, you know there is no CO2 in the water, but a whole lot of O2,


Just wondering.I did a lime water test so i was just wondering.

So can they die from too much O2 and no CO2 does it affect them at all?

Thanks.

No, they cannot die from a lack of CO2, remember plants respire too, so they're producing CO2 all of the time.

I thought plants take in CO2 and release O2

In photosythesis, yar. But they also respire (like all living things) which uses the carbohydrates made during photosynthesis and breaks them down to get energy, using up oxygen and producing carbon dioxide.

All animals need O2 to breathe and live. CO2 can only be used by green plants for photosynthesis, animals don't need it and very high concentrations of CO2 are toxic, causing animals to suffocate.Don't worry this doesn't apply to fish in aquariums, just large mammals/reptiles/birds left in cages with no ventilation.

Red plants photosynthesize too, but more light is required.


Also CO2 levels higher then 35-40ppm can cause problems in fish tanks, fish may begin to gasp.

Well said.

No lack of co2 will not kill your fish. Lack of o2 will.
