For the past three weeks I've been fighting an invasion of dark green algae. This stuff grows faster than I can blink. It's not very thick, but has attached itself to all; it is on my driftwood, my plants, my decorations and even climbing up the glass. My snails, my farlowella and my shrimp don't seem to feast on the algae. My tank temperature fluctuates between 79 F and 82 F, if that of any help. So, is anyone able to identify this algae and/or suggest a possible way of controlling it? Talk about an invasive species. Jason S.
