Yellow sponge nuisance (not pineapple)

[danfee]

Anybody have any input on removing or reducing this yellow sponge? Surprisingly very little info on it on the internet.

I read someone say that it can take the calcium and carbonate from rock and cause it dissolve. Well, I have it on my dragon soul torch colony stalks and one day one stalk literally just fell off. So I’m wondering if any truth to that.

Its usually just growing under rocks and sand but can creep up under some bigger euphylia colonies. Definitely doesn’t like light.

Tried scrubbing off during a water change once and didn’t really do anything. It’s pretty rough stuff.

It looks to be soon to be taking over my tank.

Any input sure would help.

Any idea if silicate is in your rodi water?

Never checked my ro/di and haven’t done an icp test in over a year, but it was good when I did test.

Some dwarf angels may eat it. However, I find sponges are often limited by silicates.

It grows in my tank. It’s growing on one of my elegance corals (for 10 plus years) but hasn’t killed it. I pull it off when possible but otherwise deal with it. It grew much faster when I carbon dosed and is one reason I stopped.

I don't want to make this post too dense to read, so for telling if the sponge is harmful or not and for info on ways to remove it, see my post linked below:

Growth id?

New to coral, noticed this a couple days ago. At first I just assumed it was the zoa spreading, but now I am not sure. Should I be concerned? It’s not really noticeable when they are open. The last pic is when I noticed it, the other two are this morning.

Boring sponges can dissolve calcium carbonate to bore through the rock, but that's only boring sponges - your sponge seems to be an encrusting sponge rather than a boring sponge, so I wouldn't expect issues with this.
