My refugium looks like an unmaintained fish tank. I have tons of micro and macro algae in there. I know that's the reason I have it, but when do I clean it out and how much of the algae do I remove to make it still effective? Also can I remove caulerpa incorrectly enough to release something into the water and start problems in the main tank? What does it mean when the caluerpa goes asexual if that's the right term?
Thanks,
Tom
