Please log in for more thread options You may very well have diatoms. This is perfectly normal in a newly set up
tank. They typically feed off silica as their main food source and once
that is depleted, they will die down. This usually takes a few weeks to 2
months. My 240gal just finished it's diatom cycle and we're near the end of
the die off. The rocks have their natural color back, the bog wood and
plants are all looking "normal" again. It's really not much to worry about
unless it lasts for several months. Then it usually means you have surplus
silica somewhere getting in the water (and no, the silicone adhesive is not
a source).
Another option would be red algae, I usually get this dark maroon algae at
the water return spouts. Again, I'm not too concerned about it there so
long as it doesn't impede the water flow and grow out of control.
The post about the UV can be a good suggestion. I have one on my tank and
they can severely help control waterborne algae and parasites (like ick).
