 Re: Brown Algae
Yes, once the nutrients in your tank have been depleted, the diatoms will be reduced to minimal/non existant levels... and then you get the wonder of the green algae.
In response to your concerns about the liverock and the loss of your corraline algae: Any change of lighting conditions will cause a massive change in the symbiotes that inhabit the actual corraline algae. These symbiotes are what gives corraline its red/purple color. Any increase/decrease in light intensity or light duration can cause this change. Luckily, after a couple weeks, and your photo cycle is on a normal pattern (invest in a timer if you dont already have one), your corraline will start to repigment itself. This hobby is about patience and waiting... and waiting.... and waiting. And just when you thought you've waited long enough, you wait some more (And then a little more after that). |
