I think that a tube of Gore-Tex running through the algae tube might work 
(have the tube open at both ends with one being input and the other exhaust, 
no real bubbles), but you may need to have something closer to human lungs or 
two tubes set up to bubble your breath through the algae and the other to 
collect the oxygen produced by the algae.

If you make any headway with designing a system for a sub, let me know 
because I'd love to have a system like that on my sub when I build it.
