Brown Substance?

Recently there has been this brown rusty colored residue covering the decorations and even the live plant. I'm not sure what it is, but every time I scrub it off the rock the next day it's back. What is it and how do I get rid of it?

This is a type of brown algae that signifys that you have a mature aquarium. Best thing to do is to scrape it off. Expect to need to do this once a week for decor and tank sides.

What you have is an outbreak of diatoms. Common in new aquarium. They feed on silicate. They will go away on their own in time. But to speed up the leaving ottos love them as do nerite snails.

Thank you! I'm glad it's not a sign of a dirty tank. lol

I hope so, I don't mind cleaning the tank often but definitely not once a day. (I would if I had to though.) :dead:
