Brown Slime - Possible Blue-Green "Algae"

[sacrifice333]

Thanks for the tips so far.

Two things I didn't mention were that a) I bought a new bulb in November, so the spectrum should be decent and b) water changes that I do are approximately 10% once per week (which sometimes ends up being 15-20% every two weeks) with RO/DI water.

For a skimmer I'm considering a Remora hang on type.

As for a refugiam, I don't know much, if anything about them... but I'll do some research.
