Sump macroalgae covered in micro sea spiders

[Bugenar]

I just finished my war with the red planaria, and now this…

I saw baby cardinal fish in my overflow and saved them, grabbed macroalgae from the sump for them to hide in, and saw these little spiders all over… There is a healthy pod population in both my tank and the sump.

I swear I’ve seen these before in my tank but I lost it and never saw it again. no lps or sps deaths. zoas, acans. polyp coral are all healthy

does this work?

there are also sponges and tons of tunicates in my sump… not sure what these guys are eating but clearly no effect on anything
