tons of bubbles on drift wood

[oenology]

Lately I have been getting tons of bubbles forming all along the peice of drift wood I have in my planted tank. Is this something I should be concerned about?

Is it a new piece? It is normal with a new piece. If it an old one, maybe there is a change in water parameter, i.e. rise in temperature or hardness that might squeeze whatever air left inside the wood. Don't ask me how to explain it. It is just a wild guess.  :roll:

If the wood has been in the aquarium for some time, and it is in fact driftwood and not green, and the bubbles are not as a result of the addition of new water, then I would conclude you have a mystery on your hands :?   Very weird indeed.  The only possibility that I can suggest is that the wood always contained some internally trapped air that has found a way of escaping.  If so, I doubt if this air would be toxic.  Opinion of course.

The wood has been in the aquarium since I set it up about a month ago. The only difference is that I added another flourescent to get 1.5wpg. The bubbles started to form about a week after. I'm wondering if they are a byproduct of algea photosynthesis due to the increase in light. The fish seem fine and active. My ryunkin is getting so round and he is so greedy that when he goes for food he often ends up upside down but that doesn't stop him. He's a hoot to watch.

Harvest the bubbles and set a match to it.
You don't have algea and your tank is not over oxygenated.

Well, I still think it must be plant-life related because this morning (early) all the bubbles are gone (night time respiration). I'll see if they reform throughout the day while the lights are on.

Is it correlated to water changes?  Could be a result of degassing.

Yup, the bubble are back. Where are all the plant biologists? I'm sure it has to do with respiration/photosynthesis. Although maybe Julie is right and it's degassing - warmer during the day when the lights are on = lower O2 saturation. Night time, lights are off, water cools, O2 saturation goes up.

If this continues to go unexplained, I may want to collect some of the gas, as pegasus suggested, but have it analysed.  You likely  have some scholastic contacts/colleagues that could break down the gas and offer some professional opinion as to what is triggering the expulsion.  Interesting.

From what I remember at college aerobic decay organisms often produce co2 during respiration. I think its anaerobic ones that produce Ethleyne durring respiration.

Could it be that after a month or so a population of organismns has become sucsefull withiin your wood and are breathing?

Keep and eye open for changes in carbon if you have a test kit for it.

I went to school at the Provincal Agriculture Research Facillity in Kemptville. They used to have  extension services there for the public, but I think they do everything in Guelph now. Its not Ministry Of Ag anymore. Now its part of the University or Guelph Business group :/

That's what I had implied in my reply..... could it be methane gas or co2 since the bubbles seems to be always on the same section of the wood piece?
