anybody know what this stuff is gone in the morning but comes back in the afternoon. I'm thinking red slime but tank has flow. Water change works but only for a day or two. Parameters are all where they should be.

I expect it is cyanobacteria, but there is a possibility it is dinoflagellates.

If you swipe at it, does it easily come apart (cyano), or is it snotty (dinos)?
 
What's the easiest way to get rid of them. Can to much flow cause it. I did recently add another power head said id have a problem with GHA. Still have a little but not a lot
