I'll be following along, I'm dealing with a bloom of something right now. About 2 weeks ago I tore my rocks down to catch a couple fish and rearranged a bit when I set back up, so I think that has something to do with it.

I have a question. How do you distinguish between dinoflagellates vs. cyanobacteria vs. diatoms (without a microscope...)?
