Coraline algae falling off in sheets

[Pennywise the Clown]

Most of the year I have a thick build up of coraline algae on the back glass of my Reefer 250.
Recently is has started to break off and over the last few days it has come off in sheets, several inches long. It is still pink in color but now lying on my sand bed.
I have lowered my alkalinity lately as I was starting to get burnt tips on my acros but it was coming away before this.
It is starting to get cold here in the uk and I don't know if this has anything to do with it.
Any ideas?

Mine does that too. Once it gets really big, it falls off in big sheets. I thinks that’s normal.

Good to know, thanks.
Do you remove it? Mine is mostly behind my rock work so not really doing any harm.

I sometimes remove it during maintenance. If it falls behind rocks, I let it go. I don’t think it’s a problem.
