floating plant
I have been thinken lately about getting floating plants for the aquarium and have two questions:

Do floating plants get their carbon and oxygen from the air or water, maybe both?

Will floating plants limit the gaseous exchange between atmosphere and water surface and when the floating plant releases these gases is it into the atmosphere or water?:-)

o-o Those are some complex questions.

My best no-research guess is that the plant would take CO2 from where there is the highest concentration (in the air) and release O2 where there is less concentrated gas (the water)... like osmosis... But I'm not sure if that's right at all haha. I feel like that's not something people would have tested out.
I know floating plants do like to take a lot of nutrients from the water...
You know your fish won't care either way. ;-)

Hello Olympia:

Thanks for the best guess answer.
I did not mean to ask the wrong type of question, so as a moderator please move this thread to the trash bin.
Itís one of those situations where the cat-fish is caught by curiosity and there is no satisfaction to bring the cat-fish back. :lol: :lol:
