I have a new issue. It's always something. I thought I had some cyano cropping up, and it's usually fairly straightforward to get rid of. I was going to scrub it off the rocks with a brush and it won't come off. I mean, it is tough stuff. In the distant past when I've had cyano I could dislodge it with a baster.
Any idea what I might be dealing with here?
