What’s going on my live rock?

[TheNewClownFish]

Hi all,

I have this old live rock (7 months) I transferred into my new tank. It has some stuff that I haven’t seen before growing on it. Any ID?

Aren’t sponges supposed to be more like a fuzz/smaller? This is all over the rock. Kinda like cobwebs

Not necessarily, sponges are incredibly diverse, but a clearer/close up pic would confirm

Looks like a calcareous build up but need a clearer pic

For the sake of future forum readers, say you had a calcareous build up, what would be the solution?

Hi, are you able to see this more better? Sorry for the quality

Some research makes me think it might be bryozoa

May be calcareous buildup as mentioned, though when you look at it up close does it branch upward and/or have very small branches coming off the sides. Do they look like hollow tubes up close? If yes than I'd say sponge

Thanks, what is calcareous build up and how do I fix this? Sorry for the silly question

Here's one I found on another thread, this is what I'm talking about, also have tons of this stuff in my tank

I may be wrong but if I remember correctly it's caused by low flow, which caused by debris settling, increasing the flow may work, though I may be wrong.

I see, thanks for the help!!

Out of curiosity, does it look like the photo above?

This looks like filaments when coral is trying to digest excess nutrients,and use these filaments to obtain food in various forms , or even when nutrients are low and .. . . . even happy coral will display this known as mesentrial filaments. If not is clatharina sponge but pics are fuzzy to fully confirm

I was thinking the same. I have bryzoans in my tank. Mine tend to be more branchy, but still very small, like 1/4 inch long at most.

Is that the normal position of the rock? Or is that the bottom of the rock and you flipped it up for the pic? Is it hard or soft? Does it remove easily like with a turkey baster or light tooth brush?

Its definitely a sponge, mesenterial filaments do not branch and are thin/flat. I have that particular sponge all over my rockwork.

Yeah- I’m sure clatharina
