So much blue, can't see anything (or I'm too old

). Red slime is soft, thin like a silk, you can remove easily by siphon if hard might coraline

Ok, I can see it from the last picture. I think, it's coralline

I'm not sure if I misunderstand what you mean. Coralline will increase anywhere that the light can reach. That means your calcium, magnesium are in ideal parameters. Typically, it takes few weeks to grow, it appears on glass, you need a scraper to remove.

Coralline is a PITA to get off the glass no matter how big it's gotten. You'll definitely need a scraper even for tiny bits. A cloth or sponge usually won't do.

Also, yeah, I'm thinking it's coralline. I find that the red varieties tend to grow only on rock, though, so maybe I'm wrong. If it wipes away with a finger swipe, it's definitely not coralline.

Sounds like the glass stuff was red algae and the rock stuff is coralline. Keep your eye on the rock stuff. If it grows slowly out in all directions, it's coralline for sure.

Edit: Sorry, i now see that you included the part about wiping it in the OP.
