Someone told me this looks like a sponge - please help ID it. It killed my entire Xenia colony quickly. I took the rock out and exposed it to air for a while and brushed the remaining fragments of Xenia off, as I read to do this on R2R somewhere. I’m looking to put another Xenia frag there. Should I wait or is it safe now? Tank is five months old and started with pre-owned live rock. Could this (sponge?) have come from that?
Also, what’s going on with this sand? I think I passed the diatom stage and I got rid of cyano months ago, so is this diatoms again or maybe dinos? I did see a bit of bubbles on some brown goo on a piece of a rock but now it’s gone. I used a turkey baster to blow off some brown slimy stuff smothering some of my corals. I saw on YouTube that if you can blow it off then it’s likely not dinos. Any ideas? I added a UV light and will be adding copepods tonight to try and fix this issue. I had a few things die from a salinity or pH issue recently, including that urchin in the pic, so ignore that.
It’s been a challenging two weeks.
