Can plants use BiCarbonates?

Had a discussion about BiCarbonates..

I seem to remember that many plants can use the CO2 from BiCarbonates..

But can't remember the exacts...

Anyone care to chip in?!

Specifically getting CO2 from KH etc.

 

Re: Can plants use BiCarbonates?

hmm...
yes, hmm..

the argument is that "only" these; Elodea, Vallisneria & Ceratophyllum can use Bicarbonates?
I seem to remember something about these species, but not what specifically.

As fart as I can gather from various posts, and tom's reports, Plants can use Bicarbonates as a source of CO2, IF there is no CO2 in the tank.
This would affect the tankwater's KH and slowly lower the KH.?!

 

Re: Can plants use BiCarbonates?

The 50 you mention are plants that DO use the bicarbs?

as I've read what you've said in reports and stuff, about 50% of all plants can use bicarbs, but, as you say, only a few species use bicarbs readily, even though CO2 is present?

Am I understanding this correct?!

This is about what i've come to, also what I gathered reading an article from tropica; http://www.tropica.com/article.asp?type=aquaristic&id=142
