OK, I was just searching for CO2 stuff, as I can't wait till I get a pressurized system, the yeast method is soooo unpredictable. Anyway, I came along this "reactor", which they called a diffuser. It can be seen here CLICK ME!!.

Now, I am not getting my hopes up, because it seems like one of those "too good to be true" things. Also, I don't know the exact size of it, but how does it work?? I don't see anywhere even an intake tube slot for CO2 or anything, I'm sorda suspicious. Has anyone had any experience with this reactor or is it even for injecting pressurized CO2? I just need to tweak my powerhead/gravel cleaner reactor, but if I could get this thing, it would be a lot easier. Anyone got info on it?

A diffuser works by atomizing the co2 gas into very fine mist-like bubbles that'll disolve more readily into the water column. I have several "theoretical" problems with them. I say this because I don't use one and I don't know anybody that does.
1)the membrane seems like it could get clogged easily with contaminants in the gas supply or the water column which could render it useless.
2)If there isn't a sufficient current running past the "mist" a lot of the gas could escape to the surface of the tank.
I think that problem #1 is probably a very real scenario. IMO, I think you should tweak your gravel tube reactor a little more.

Thanks for the reply. While under certain circumstances, it would probably work, but wouldn't for me. Water changes, water changes, water changes.....
