I have just set up a new marine biorb (60l) which has live rock and two turbo snails (Spathiphyllum sp.). It has been running for 3 weeks now. I am not new to fishkeeping, having kept coldwater fish as a child and tropicals a few years ago.

Brown dust like algea
I have had a brown dust like algae on the bottom third of the acrylic surface since setup (beginning of April), which seems worse after a water change. It is also settling on other areas of the tank but is not long like hair algae - is it likely to be diatom algae? It does wipe off easily but I just wondered what it was.
