It might be important to remove the excess algae. I've seen a couple fish
get trapped and die in that sort of hair algae mess.

I was told not to expect many more algae-eating shrimp to be shipped until
spring. The livebearers you're thinking of are probably Ameca splendens.
Ameca splendens are more expensive and not as widely available as many
other new world livebearers. The more common and less expensive mollies,
platies, guppies and swordtails all graze on hair algae. Mollies are well
known as algae eaters, the others may do well at controlling small amounts
of algae but probably won't touch a big problem.

I think if you shut off the CO2 you will do more to hurt your plants than
you will to hurt the algae. You might try fertilizing your plants with
either spikes or tabs in the substrate. That way the plants (at least the
rooted ones) get fertilized, and the algae does not.
If you do use substrate fertilizer then you may need to take care when you
shift back to water column fertilizer later. If you fertilize the water
column before most of the substrate fertilizer is used up you might end up
with excess fertilizer in the tank and yet another algae problem.
