Ralfsia expansa algae

[milano07]

After a lot of research I have finally found the name of the algae that I have been fighting for the last few months. This thing is called is Ralfsia expansa and I wonder if you any of you has had this same problem. If so, I would like to hear how this thing was defeated.

Here is a bit of info about my tank. It's a 40 gallon tank that has been set up for years. The skimmer is a MCE600 and I do bi-weekly water changes. The tank inhabitants are a pair of clown fish and that's it.

The only thing that I have done differently lately was to go from a MH fixture to T5 fixture and I wonder if this change is the cause of this algae problem.

What eats this thing if anything....?





Thanks
