Ok so while searching around on the internet while at work...(Ok its not what I should be doing but otherwise I would be bored) I've found this thing called a CO2 difuser that is supposed to be good for the plants in teh tank...So here are my questions..Has anyone else heard of this thing? Does it actually work? and will it harm the fish?

I just stumbled upon this, and noticed no one answered.

A CO2 diffuser alone does nothing. It is, as the name implies, merely a means by which CO2 is diffused into the tank. The co2 has to come from somewhere, and is typically one of two sources for aquaria. That is, either DIY yeast fermentation, or a pressurized CO2 cylinder with a regulator and needle valve to fine tune the amount of CO2 entering the tank. You then run either one of these systems to the diffuser, and it makes the CO2 bubbles into a fine mist, allowing the CO2 gas to be dissolved into the tank easier.

From what I read about these things on practicalfishkeeping.uk is that this diffuser is for larger tanks that need CO2 diffused throughout at a steady rate. For smaller tanks I think you only need those little CO2 tabs... My 10gal uses half a tab every 5-7 days only.

Maybe this article will help!
