You're suggesting bicarb can be used instead of co2?

But Tom - everyone nows bicarb is good for gas.

Bicarbonate and CO2 uptake
 

Hi..

http://www.publish.csiro.au/paper/PP9790499.htm

Hmm.., so bicarbonate might locally be willing to allow the
plants a CO2 credit they would have to repay in CO2
(later)..? ;-)

I took it to mean "plants will take carbon out of carbonate" which anybody whose
read the 30 year old Dupla book knows. They just quantified it.

book knows.

Hmm.., is "your" carbon == the element carbon

or

is it == CO2..?

Same thing. Plants use carbon they get from anywhere - c02, bacarbonate, Flourish Excel...

I got that far, and like you, I've known about biogenic decalcificaton
for a long time. pH crashed quite a few tanks with it. LOL! That's
what got me to try CO2 the first time. I got tired of spiking the
planted tanks with baking soda to put the carbonates and buffering back.

What I couldn't figure out was whether the plant prefers carbonate to
CO2. I wasn't sure how to interpret "The total resistance to bicarbonate
uptake appears to be 8-12 times that for CO2 uptake presumably due to
the processes of active uptake, transport and/or conversion to CO2
involved in bicarbonate but not CO2 assimilation"

Well, let's dissect it. Nurse, scalpal...

The total resistance to bicarbonate
uptake appears to be 8-12 times that for CO2 uptake presumably due to

Ok who cares about presumably or why they think it acxts like it
does, how does it act:

The total resistance to bicarbonate
uptake appears to be 8-12 times that for CO2

I take this to mean plants can uptake CO2 8-12 times more easily than
bicarb.

But who cares, bicarb works? Cool, one more thing to play with.
