Pest Algae

[CandyCane]

So recently my tank has started to grow a long, stringy brown colored algae that grows mostly during the day. It prefers area's with high flow and grows on the glass the thickest. Any idea why it may have shown up all of a sudden? My corals don't seem very happy with it.

Do a search on dinos, you're not going to happy about this.

Some further details on your tank, how old, how big, flow, chemistry, lighting, bulb age. anything and everything you can write up for us will help.

I did some further reading and a lot of people say its a diatom bloom.

My tank was set up in august.
flow- 2 return outputs, 2-24 koraline powerheads
In need of a water change prob pretty badly though, havent had time with school.

Think it could be just a diatom bloom? If not I'll post more info

Diatoms are usually a brown powdery dusting rather than stringy. If you can get a pic, that might help..

Ya thats what I thought to. Also this stuff produces bubbles so ditom bloom sounds off.
The pic isnt of my own tank but its the same stuff
