As Hobbsy has said, they can start to grow in new and or cycling tanks, and they can go away after a little while, usually once you get into a normal cleaning routine. It can also be caused by silicates, phosphates, high nitrates, and not enough light.
Phosphates can come from your tap water, fish food, and fish poo.
Your fishes waste is where the nitrates come from.
And the silicates usually come from a few kinds of sands, that people use for substrates - sometimes it can come from glass.
So a few things you can check.
1. You can check your tap water for phosphates.
2. Test your tank water for high nitrates.
3. What kind of substrate do you have? Play sand?
Things that you can do to treat the problem.
1. If you have high phosphates in your tap water, then you might have to concider using a product like PhosBan or Rowaphos.
2. If the tank water is the problem, and has high nitrates and/or phosphates, then you need to do large water changes - at least 50% per week - and gravel vacuums to bring those levels down.
3. Look at your feeding technique. Are you feeding the fishes too much? Are you feeding them once a day, twice a day, or three times a day? If you're feeding them once a day, then there is a fair chance that you're dropping far too much food in the tank for them to eat in one go. Whatever food isn't eaten will settle in the substrate, rot, then it's producing nitrates/phosphates to build up in the water. I feed mine three times a day - three small serves. This way they all get some food, but it's all eaten.
4. If you have play sand as the substrate, get rid of it and get something else to replace it with. The silicates can leech out of that sand for ages, and continue to cause these diatom blooms.Three-fourths of the Earth's surface is water, and one-fourth is land.

May i ask what kind of gravel / sand u are using? I went the cheap route with silica based sand and ive been plaqued with diatoms from the start. Its possible the cycle has be ended by not treating ur tap water.... But diatoms take a few months to kick in to gear some times.
If like me you have a silica based sand or any silica based orniments ie geodes then you will have to remove them inorder to rid your tank of them.KING OF THE GOLD BARBS RAWR!!!!
I wonder if i plant one of my tiger barbs would the demon seed grow to a full tree?
gotta love them bunnies!

My tap water read 2 in phosphates, which is high. Then I bought playsand for my tank which is silicates. I totally removed the sand after 9-10 months and gave up on it. escamosa is spot on that it might require silicate/phosphate sponges in your filter.
I'm as patient as the next person but it got to be too much work for me.

I've got the same problem, but it is my plants that are covered. Does API sell a phosphate test?130g: 4 Angelfish, 2 Roseline Sharks, 12 Conga Tetras, 5 Kuhli Loaches, 1 Otocinslus, 1 Corydora
