No, they only use CO2 in the form of carbonic acid when dissolved in water. They cannot use bi-carbonate as a source of carbon unlike some other plants.

Moss cannot use dissolved CO2 ???
Hi, read somewhere about growing moss...
When CO2 dissolves in water it forms carbonic acid (H2CO3)...Lots of CO2.
KNO3 and PO4 and they do quite well.
Even at higher temps, they do well.
Mosses unlike many aquatic weeds cannot use HCO3-, they must get all their carbon from CO2.
Colder water possess more CO2(and all gases) than warmer water, but if you add CO2, you can easily address that issue.
If moss dies rapidly, you likely have either Copper/algicides present or not enough CO2.

so does that mean that the dissolved CO2 we inject into a moss tank is totally useless to the moss?

thats sound interesting, meaning even if we at baking powder into the tank it will not help the mosses at all isst?
"Ask the Lord your GOD for sign, whelther in deepest depth or highest height."Isaiah 7:11
Baking soda is used to increase the hardness(kH) of the water.
Cheers!
I see... but i was taught to use baking soda to be added to increase the bubbling of the plant... so its hardness and not CO2...Originally Posted by kadios
Thank You
"Ask the Lord your GOD for sign, whelther in deepest depth or highest height."
The fact is most of the CO2 that dissolves in the water remains as CO2(aq). If I don't remember wrongly, only about 5% of the dissolved CO2 converts into carbonic acid.
CO2(aq) + H2O <----> H2CO3 <----> HCO3- + H+ <-----> CO3-- + 2H+
Moss only use dissolved CO2, not bicarbonates or carbonates.
Adding baking soda increases carbonate hardness (KH) or alkalinity (IMO a better term) of the water. Hardness usually refers to general hardness(GH), the concentration of Mg and Ca in the water.

Does this mean that seachem excel is useless for moss? since seachem excel is a form of organic carbon...
I am not sure about this. Maybe you can try emailing Seachem on this. Their customer support are quite responsive to this kind of enquiries.
