IIRC it was tested on a small scale and didn't work. Fish ate the algae before it could settle on the sea floor.

I know settling to the sea floor is the intended result, but locking up more carbon in the steady state biomass of creatures would do the trick too. If we did this continuously could we just grow the biosphere?

It may vary with scale. Similar to how swarming populations (cicadas) can saturate the local predators.
