I have just been vacuuming the diatoms off during water changes for the moment. The plants and corals don't seem to be suffering, and it's slowly going away as the plants take over and I get the chemistry into better balance.Swimfins said:Those blue eyes are piercing. My mermaid fern got cyano covered and I just fresh water dipped it, shook it a bit in the water and it was ok afterward until my blenny decided to eat it. Might give that a try.
