Question Best CO2 Diffuser

What is the best (affordable) co2 diffuser? I am currently using the fluval ceramic disk but lots of the small bubbles escape to the surface... or is that normal???

If you have a canister filter, build a rex grigg or cerges reactor. If you DIY them they are very cheap and will work as well as anything.

I'm using an AquaClear HOB with the Fluval ceramic disk and had the same problem. I rearranged my equipment so that the disk is almost directly under the filter intake like bsherwood mentioned doing with his canister intake. The results have been very good.

+1 to rex griggs style reactor if you have a canister filter. Can easily make them out of PVC and nylon fittings for like $10

I use a fluval ceramic disk mounted on the back wall of the aquarium and a hydor power head mounted on rear of the right side glass aimed at the stream of bubbles. It blows the bubbles all over the tank, very few ever reach the surface.

I personally have found the fluval ceramic disks to be very inconsistent and harder to work with certain BPS rates. I like the small glass ceramic diffusers more.

I like an atomizer if you have a canister filter. I've used the generic UP Aqua one and it was very effective.
