How does everyone diffuse their CO2 and why?

I'd be interested to hear about opinions on efficiency.

Also views micro bubbles versus completely dissolved CO2 (i.e. reactor). Please include as much detail as you like.

Venturi. Because it works.

Venturi also....

I have tryed the "bell" method with little or no results, but I currently use two latters, and one into the inlet of the filter, they seem to work ok as long as my water is not being agitated much on the surface. Cannot really tell difference because the CO2 diffusion is at different rates on my DIY. Hopefully up grading a tank soon though!

Micro-bubbles i.e. ceramic disc works well under heavy flow, or under the intake
Hagen Ladder works well too, but can be difficult to hide.

I prefer my glass difuser to the hagen, but I am currently using both.

ok, I turned it into a poll.

I use an in-line reactor but may try a diffuser to see the difference, if any.

In-line, Rex Grigg type, DIY with 1-1/2" PVC pipe, about 18" long.

I am surprised by how well niko's chopstick method is working. Just be sure to use a round chopstick, the square ones don't work that great

In line reactor, tried diffuser, decided it wasn't for me.

I use a Hagan ladder... It works for my plant needs!
