Red algae: Also called Black Beard Algae (bba), or Black Brush Algae. Short hairs (1/4" long), closely packed together. Appears dark green, black, or dark red. Grows on plant leaves, and sometimes on decorations/substrate. Often grows all around the edges of plant leaves. BBA thrives in situations of high phosphates. Phosphates come from fish waste, excess food, and occasionally will be present in the water supply. The best way to eliminate BBA is to let the plants out-compete the algae for the nutrients.
In heavily planted tanks, BBA will often show up when the plants have used up all the nitrates. This causes plant growth to slow or stop, which leaves the excess phosphates available to the algae. By supplying extra Nitrate to a planted tank, we allow plant growth to continue until all phosphate is consumed. Then plant AND algae growth will slow/stop. As long as a usable (5-10ppm) level of Nitrate is maintained, the the plants will continue to use up the available phosphate, effectively controls BBA and other phosphorus-dependant algaes. See the article "Adding Nitrate to a Planted Tank" for detailed instructions on how to increase your Nitrate levels.
Very few fish will eat BBA. The most famous one is the SAE (Siamese Algae Eater). I've got 5 of them in my 75g. I added several BBA infested stems of Bacopa to the tank recently, and overnight, the SAEs had completely cleaned it. But even these amazing fish won't be able to control it you don't have the phosphate level under control. Another fish rumored to eat BBA is the American Flag Fish. In tanks with very large amounts of BBA, the BBA covered leaves should be removed once the phosphate level is controlled.
