Answer
Hi,

First of all, I have some questions.

How long has the tank been set up?

My guess is it's a recently set up tank and the stuff you're seeing there looks, to me, to be what's called Brown Algae.  It forms when nitrates and nitrites and ammonia begin to cycle in an aquarium.

That would mean the tank has not finished its cycle yet.

How long has it been up and running?
What are the readings for nitrite, nitrate, ammonia and phosphates?

Please let me know and maybe I can give you a full answer. :)

Thanks,
Renee
