Begins as brown patches on the gravel and/or glass, then rapidly coats most surfaces of the aquarium with a thin, dark brown coating that is easily removed. Unlike blue-green/slime algae, it does not come off in large slimy sheets.

Even if your aquarium is not in direct sunlight, the fluorescent light over the aquarium may provide enough energy to support algae. If you leave the light off completely, the aquarium may clear in a few days. Then, you can gradually increase the light duration until the water starts to become green again. Size
When selecting your gravel you need to take into consideration everything that is going into your tank. High water flow angled downwards can cause a problem with tiny gravel. For ground walkers and snails small gravel may be the better choice. Plecostomus will love to munch on large pieces of gravel as they suck off the algae and many shrimp enjoy holding the large pieces in their many hands as they eat. Plants can easily spread their roots in both sizes, and algae can sink further into large gravel. Some fish even like to burrow into small gravel!
Ultimately smaller gravel need less, but more difficult, maintenance and are favored by most creatures. If however you own only free swimming fish and cleaner shrimp large gravel may be more your style. If you have tank mates who require different gravel you can even get two smaller bags of each, getting the benefits of both.
While this is a choice of preference we still want to make sure new owners don't buy without thinking ahead. Sure green gravel can look beautiful and provide a rich background. Add in a couple plants and there's suddenly too much green. Likewise with black gravel it may be too dim if you have dark fish with few decorations. Remember the aquariums are supposed to be unique and vibrant. Try a color you don't see every day or even mix two colors together. Solid black combined with grey stones can give you a rich charcoal effect while green and pink produce an uplifting spring time vibe.
Savvy owners can even match and contrast their gravel with their fish. Everyone knows the combo of glow fish and black gravel. Dazzle your visitors by contrasting black and red fish with a lighter color. Conversely white/silver fish with dark colors can make a beautiful pairing.
If you do not want any live plants and have few scavengers, just an inch will serve your tank well. This will save you both space and money. For those tanks full of plants and various burrowing fish a 3 inch deep bed creates a more suitable environment One of the first signs that your aquarium is developing an algae problem is the presence of particles that are greenish or yellow-brown in color. Aquarium algae can also take the form of white or gray filamentous masses that are composed of bacteria and fungi. Your aquarium may be visited by more than one type of algae at a time, don’t be surprised to see a mix.
