Odd new algaes that have appeared in my sump below my scrubber lights

[Rumpy Pumpy]

Cleaning out today, I noticed two odd algaes, growing on some small live rock pieces which I keep in my scrubber/sump






Never noticed them before & never had anything like them growing anywhere in my system (and haven't introduced anything new in ages). Strange how these things can just show up after years.

Might move them to the display later on and see if they can survive.

Looks like Codium.

Looks like Codium.

Could be, hard to tell. It's like little translucent tubes at the moment.

The 2nd one is that "lettuce leaf" type stuff. Ulva or something like it.
