I have used a diatom filter to remove an explosion of floating green
algae (so thick you couldn't see much of anything). After 24 hrs the tank
was sparkling clean. Unfortunately, the green algae seems to inhibit other
forms of algae which are more difficult to deal with and now I have much
green and brown fur algae. Well at least the fish like to eat it and there
is little chance of starvation even for long periods if you're not there 
to feed. Algae also helps fry as there is a continuous supply of food! 
They seem to grow much faster with this.

Continuous diatom filtration might not be advisable since it would remove
too much microscopic food for the fish. I wonder if it might be useful
for controlling other non-floating algaes which spread through water or
infest a tank via air-borne spores? Does everyone keep fish in their plant
