If the brown stuff is brown diatom it can be easily removed by adding otocinclus or other algae eater into your tank. Brown diatom is caused by excessive amount of silica or silicates in your tank. You can read more about brown diatom at this website.
I personally like brown diatom as my otocinclus love them. My tank is starting to get covered with this rust covered algae. It started in the sand bed and moved to my live rock.

There are a few reasons why these patches of rust might be turning up in your aquarium. The most common reason is that the tank was newly set up but it could also be the result of poor tap water quality certain substrates or light and nutrient imbalances.

If you have owned a fish tank you are probably familiar with the dreaded brown film that can quickly take over its interior. This film is known as Silica Algae or Brown Algae and it begins as brown patches on the gravel or glass of the tank. Once established it can rapidly coat most surfaces of the aquarium with a thin dark brown coating.
One example is the blue-green cyanobacteria which has the appearance of rust-colored algae growth when in bloom. While a buildup of cyanobacteria is certainly inconvenient it rarely produces damages to aquatic life. What is more the slimy mat they create is easily removed from the fish tank through a simple siphoning process.
Rust and brown algae both look in the same color which is brown. Rust forms on metal surfaces and brown algae forms on any surface including metal. So if you have some metal objects in your tank you may mistakenly think of Rust as brown algae.
Hence knowing how to check the difference is essential. It is brown algae aka diatoms. So very common in new tanks and if the water has a lot of silicates in it may persist though usually only in a few corners or the filter tubing perhaps.

Blue-green algae or cyanobacteria. Since BGA is photosynthetic you can try to blackout the tank for a week but this can be hard on the plants.

It is likely algae which comes in different shapes including that which looks like rooted plants with leaves and colors including pink and purple and a burgandyrust color that I had quite a lot of. Id need a better description to tell you the type of algae. Ive tried numerous things to get rid of this rust colored algae on the white sand.
Ive done practically complete water changes several times. Ive changed every filter in my Rodi unit. Ive changed filters all together.
Ive reduced the how much Im feeding the fish. Just in case your algae looks a little bit reddish is in a freshwater aquarium and its more like a rust color thats probably just brown diatom algae. That plagues most new aquariums.
If you give the tank a few months it usually kicks in and you get a lot less brown algae. The orange algae could be from your ac air handlerthe coils in mine were covered with itdue to a freon leakbut it also grows in the drip pan wout a leakit grew in my bathroom and in damp areas inside the house tooincluding a spot on the side of the mattress where a drink was spilledand it spread to the under side too.

Thanks for all the responses. On 5312011 at 1100 AM ReeferT88 said. My 40g tank is going through its cycle right now day 11 and I have rust colored spots on the sand and glass i think it is diatoms.
