< Anacharis could be the result of shading and could be normal.> Also I forgot to mention I do have duckweed up top, it covers a 1/4th of the surface. < Duckweed is a great indicator of nitrates. If the duckweed doubles very quickly then there is adverse level of nitrates in the tank and the aquarium needs a water change.
