Can Driftwood Reduce Co2?

[confusion]

I know this seems like a dumb question, but I have to ask. Can driftwood conceivably cause CO2 to outgas from a tank? Here's the deal: I'm trying hard to get my tank to 30ppm of CO2. I have a nutrafin ladder system in a 30G tank that is creating a LOT of CO2 bubbles that I then catch in an upside-down bell for further absorbtion. I believe most of it is getting abosrbed into the water. BUT, my CO2 levels are not getting about abuot 8ppm. I have noticed that the ends of my driftwood look like a soda fountain - bubbles coming off of it like crazy. I REALLY can't see the wood having that much residual air in it - there are a LOT of bubbles coming off of it. I'm watching a whole bunch of CO2 going in, but not seeing the levels go up, and seeing these bubbles coming off of the wood makes me wonder if for some reason the wood is causing the CO2 to gassify and bubble out.

Thanks!

The driftwood has been in the tank for well over a week now, and bubbles are still coming off of it. I'm thinking about pulling it out to see if the CO2 levels rise.

I have noticed a marked reduction in algae since I've been using this system, though.

I can`t see the wood absorbing co2 or reacting with it in any way...

the reason your not getting high co2 is those yeast based systems arent the best, when i had my diy system running i had 3 2ltr bottles feeding the co2 for my 60g tank. and i still wasnt reaching 30ppm

Agreed.

I'm not sure why I didn't think about it before, but I do have an air pump/bubble wand in the tank. I'm wondering if that is displacing the CO2 from the water?

This is most likely your culprit. If you deem it safe (for any fish in the tank), turn it off or reduce the output, and watch your CO2 rise.
