Instructions
Set up your aquarium as you normally would, but do not connect any air stones or other sources of aeration. Algae grows best in still water.
Place the aquarium in a spot getting direct sunlight for several hours each day. The more sunlight hitting the tank, the better the algae will grow.
Add an assortment of flat rocks, driftwood and similar items to provide a growing spot for the algae. Flat rocks are particularly good choices, since their shape allows algae to form a thick mat on their surface.
Watch for algae growth. Remove algae as needed to use it elsewhere. For instance, you might want to scrape a mat of algae off one rock and place it on top of the water in a nursery tank. The algae floats on the surface of the water and gives the newly hatched fry a suitable hiding place and added security.
