Yellow/Brown on sand.
My tank has been up about 3 months and a few weeks back I started getting a yellowish/brownish film on the sand. there is skinny strands of it waving around like seawead or something. What is this stuff, I was told it was normal for a tank this new but still don't know what it is. I will try and get pics up tomorrow but hopefully its common and someone knows by the description

Is it only in some areas? Do you have good flow?
Do post the pics, I had a similar problem that was cured by simply adding a powerhead. |

It could just be a slime algae or a cyano. pics will help. also what is your substrate? depth, ect...

Could be yellow Cyano algae. Hard to tell without a pic.

Take a look at this pic, is this what you are dealing with?
Jareth's Blog - Images This is my tank. I've noticed that mu hermits will sift through the sand, and my snails cleaned up some areas.

It almost looks like dinoflagellates, but I've never seen them in such a new tank. Is it a glass aquarium? Sometime light refraction through the glass makes shadows look yellow. Could the algae itself be more of an ugly brown? Whatever it is, it looks like a nuisance algae - get rid of it! I would siphon it out immediately before it spreads. Also you need to figure out what is causing it. Are you using tap water? Running a skimmer? Using GFO?

If it's neon green, its probably hair algae. Still want to get rid of it. Might try running GFO....

Iron Oxide Hydroxide - it is a brown powder, that abosorbs phosphate (the rate limiting nutrient of most algae). Often it is used in a phosphate reactor or a canister filter.
