Hi, still fairly new on here have a question & need help

[Saltwater2370]

Hi, I can’t figure out why my blue/purple sponge has turned pink any ideas? I’ve moved it back up towards the light to help it as I forgot to put its shelf back up last water change. Is there anything special it needs to get its color back? All my other corals are doing great, water is good just the sponge is being picky. My water is rich in nutrients for my soft corals and I feed my seahorses 2-3 times a day. I posted a before and after pic.

On the first picture, the blue & the green look like mushroom. Is that a NPS Gorgonion with them?

I did not realize that sponges were photosynthetic. I keep yellow ball sponges & red tree sponges. And in refugium “Cryptic Sponges” dominate.

I suggest you post in reef discussion not “new to saltwater”. This is not a newbie discussion.

Yeah, there are a lot of photosynthetic and a lot of non-photosynthetic sponges, but only a few photosynthetic ones are found in the hobby (typically just red and blue/purple plating sponges).

To the OP, I’m not sure what’s happening with your sponge, so hopefully someone with experience can give you an answer here. If I had to guess, it might be that the lighting change changed which photosynthetic symbionts thrived in the sponge and the color changed with symbionts, but that is just a guess.

Pics suggest lack of light and water flow based on film growth on the mushroom and the gorgonian which I have one has no polyp extension. I dont believe the film is dino but rather mulm or sediment. The gorgonian needs light and flow as well as phyto and other nutrients.
There seems to be an abundance of hydroids throughout the tank also .

My gorgonian always looks like this:
