This has appeared in the last 48 hours of adding a plant bought from the forum. EDIT: Those weird swirly things on the glass.





It's everywhere! 😵

Snail tracks? Not sure beyond that, not ever seen a snail leave tracks inside the tank!

Neither have I.

I have had snails for years anyway and they've never left any marks.

There's SO MUCH of it. And I can't spot any different snails 🙁

EDIT: It must be some kind of algae/bacteria, as it's growing by the hour on it's own accord.

might be some sort of calcium build up. have you got sand in?

Well, I'm still not sure, but I spent 3 hours cleaning the whole tank, filter & attachments. & 60% WC.

Had to use a razor blade to get that stuff off, VERY stubboorn!

Just hope that's the end of it.
