Does A Planted Fish Tank Need Air?

[Lord Spooky]

just curious.

 

[helterskelter]

Depends on if you want fish, if yes then it then depends on the number of fish and the size of the aquarium.
Remember that the plants remove oxygen at night so you may want to just use it at night, and that areation will help to remove CO2 if your using that as well.

 

[Lord Spooky]

right now theres a betta in there. SO i was thinking if i turned th oxygen off during the day teh plats would supply him with oxygen and mabey help the plants grow.

 

[helterskelter]

it's not a problem for a betta as the can breath atmospheric air through a special organ at the back of their mouth, so no u don't need air for him

 

[Lord Spooky]

sweet!

Will the plants grow at all from this?

 

[helterskelter]

if it's only the betta then no u dont need any aeration.

Betta doesn't need aeration.

Question to Helterskelter: Please explain how plants remove O2 at night? I thought the process of photosynthesis consumed CO2 and generated O2. The only way that I know for plants to use O2 is when they die and rot, but perhaps as a newbie I'm missing something.

 

[rsands]

at night the plants respire and take in o2 and give out CO2 like humans, its the opposite to what they do at day time.

 

[helterskelter]

Much as as rsands said.

Photosynthesis uses CO2 during the day and as a by product O2 is released, how ever at night the plant cant Photosynthesise so it then respires using O2.

70 fish in a 92 gallon tank and no air stones no air pumps just co2 injection which makes the plants crank out 02

gbbudd, plants cannot respirate without light no matter how much CO2 is available. They need photons to PHOTOsynthesize. I think exceptions may be things like CAM plants (succulents), that can continue synthesis for a short while in the dark, maybe a half hour at most. And those are usually things like cacti, which don't grow in aquaria. =P

light is part of photosynthesis, without light it isnt considered photosynthesis.
