White sponge growing in between zoas

[Kial]

My zoas are getting some sort or white sponge growing between them. It doesn't seem to overly bother them as they have started to spread off the frag plug.

Was thinking of removing them and maybe scraping the sponge out that's growing. Would that cause any issues or best to just leave it?

I have all kinds of areas with white sponges. I just leave them. Sponges typically are an indication of good water quality, FWIW.

These sponges are destroying my Zoas. They are bad sponges. OP - did you ever get these under control? The writing is on the wall for my prized possessions…
