Best CO2 Diffuser for 20Gal?

Hi Guys,

I'm using a pressurized CO2 system, and need a good diffuser. What is the best money can buy? (Erm...up to $80)

CO2 Reactor (Eheim)?
Red Sea CO2 Reactor 200?
Glass Diffuser?
Something else?

Thanks guys!

Do you mean something like this?

AquaCave - Detail

But how would I hook it up to a powerhead?

I'm using a nano-diffuser, good for up to 20gal. It works pretty good. I have it near a powerhead, which sucks in a few bubbles and tosses the rest around. I have a spare, which I could sell off for cheap. Just pm if you need it.

I use a pretty cheap little ceramic diffusors in my 55... works great, and most of the tiny fine bubbles disolve completely before they reach the surface. However, I also use 'fine bubble' under-gravel diffusors from Lee's for the rest of my tanks, and they are almost as good and cost about $3 for 6.

I use one of these 4 for $0.89 elbows connected to the pressurized CO2 tubing and placed half way in the intake strainer of my AC filters so that it bubbles straight up the "U" tube. Tom Airline Elbow (4Pk.) at Big Al's Online

Oops! You said best. I went closer to the cheapest. It works fine for me on my 10g and 15g tanks.
