[cgrant]

Hi,
I have read that basically purple algae is good, green and red are bad.
What about brown?
What colors are good and what colors are bad?

 

[fedukeford]

purpleish algea is good, most everythging else is bad, brown algea is diomintons (spelled wrong) which is bad, snails and hermits will take care of it

red is not bad

yea, the brown is usually diatoms, which are normal for a new tank. not all purple is good, cyano algea is a purplish red, and its not good. coraline algea is good, but comes in a variety of colors, the most common is purple, but there is also blue, orange, neon green, and a few others if im not mistaken.
