Air pump suggestion

I am currently running two Hagen Optima air pumps for my DIY Co-Counter Current air stone skimmer. One air pump is not enough for the bubble to rise to the top. Can any of you suggest a strong enough replacement ? I would like to run only one air pump instead of two.

Thank you

This one big enough?

Thanks sphelps. Looks like it would do the trick, will try to locate one localy

FYI it's pretty noisy, I wouldn't use it unless it's isolated away from your living space. You could also try a Rena Air 400 which is probably closer to two of what you're already using and would be quieter as it's still a diaphragm pump, the Coralife is a piston pump just like a compressor.

I can vouch for the Rena Air 400, using one on my air diffuser skimmer, although my system & skimmer are a tad smaller than yours. It has two outlets, both controllable, I run it wide open & it's quiet. Using a single large self made basswood air diffuser and I run the two lines into one with air check valves.

Thank you,
The skimmer is located in the access room behind the tank, but I would rather keep it as quiet as possible. The rena air 400 might be the way to go
