Re: NFC: Brown algae
Good news and bad news about brown algae. First of all it is fairly easy to
control or get rid of it. Brown algae is usually, but not exclusively, a
diatom. Diatoms require silica in the water to reproduce and grow. They
are an algae with a shell made from silicas. So the easiest way to control
them or get rid of them is to remove the silica, which is found in most tap
water. So, controling the source of the water is one way to remove them.
As of now, every time you do a water change, you are adding fresh silica
into the system for the diatoms to use to grow. Before I get yelled at, I
am not proposing that you stop doing water changes. I am simply stating
what is occuring, and why the brown algae won't seem to go away. So as long
as there is a source of silica, a source of fertilizer, and a light source
you will have brown algae.
The above statements are making an assumption that you are dealing with
diatoms, which are often refered to as brown algae. There are other algae
which are much less common which do have a brown shade.
