Is my rainbow Acan growing out?

[cmoore806]

Trying to Identify whether I have A. Coral growth at the base of my rainbow acans B. Algae on the frag plug of my torch coral (or Hydroid?) and C. the clear algae branching like growth in my sump basket.

Reef is 264 days old. No changes going on other than I've been lax for about 3-4 months without doing weekly testing. Just occasionally dosing alk/mag/calcium when I remember (I know, don't shame me). 30% Water changes every ~10 days or so maybe?

Livestock all appears alive and I have a healthy copepod population. The fish (especially Helfrichi firefish and yellow watchman goby always have fat stomachs from eating pods all day.

Light is ecotech radion G5 XR15.

Is this just more skeleton growing out the base of my acan? I poked at it, it gives a little bit like firm rubber.

Here is the other side of the acans, it looks like the structure is branching and attaching to the live rock.

Algae or is it a hydroid ???? on the plug for my torch coral

Some clear algae like growth in the sump basket:

The growth on your acan looks like a sponge. Relatively harmless.

The other two pics look like algae.

I was under the impression that a sponge couldn't survive outside the water. For sure I've had it out of water when I bought the plug a few months ago. And I started with Dry live rock and did bacteria in a bottle. Of course it could hitchhike in with cleanup crew, corals (maybe), or with additions of copepods in the past, but I'd be just a little surprised if it were a sponge. Can anyone confirm sponge?

Its poriferan sponge and is capable of overtaking coral. Keep an eye on it. If ot becomes a nuisance, you can expose it to air OR inject with air or vinegar via syringe
