Brown Spots On The Substrate..

[chiara]

Hi there,
I have a little planted tank home of two lovely angel fish and a weather loach. Since few weeks brown patches of something started to appear on the substrate and on the glass. It looks like it is spreading and now great part of the substrate (originally blue gravel) is covered with this brown-greenish stuff is it algae? Does it harm the fish? How do I fight it? Would an alghae eater help? It is really frustrating as it makes my tank look messy, please help!!

if its brown its actually a diatom. and i know this is going to sound backwards but the best way to get rid of it is to leave your lights on for an hour longer. here is a very informative link http/www.fishforums.net/content/forum/95...hl-brown-algae/

If its diatoms an otto or two would soon hoover it up they take about a day to clean one of my tanks.

What is the size of your aquarium and how long has it been setup? Diatoms are frequent in newer setups.
