What is this thick white spider web like stuff on the live rock? What can I do to rid it?

Good morning folks. I was cleaning my tank last night and pulled out the filter basket to rinse out some filter pads and noticed this alien in the bottom frame. It’s a little chunky and looks like it’s spreading. I haven’t seen this in my tank and I’m wondering if I should hit it with a...

Anyone able to identify what this is? I don’t really know how to describe it other than it looks like cotton balls on my coral. Guessing some sort of fungus? 14 gallon reef AIO, pretty new to all of this so any help is appreciated!

We just got back from 10 days away to find this weird, thick white substance in our sump (pics below). It's pure white, thick and is mostly on the display drain tube, and on the bottom of the refugium. There is some in the crevices of the live rock that in the refugium too. It blows off in...

Went on a family vacation and came back and my little guy was looking rough. I set up a QUICK quarantine tank (I am doing another one with no sand this was just an oh crap moment). Is this a bacterial infection or fungal or possibly something else? Any answers would be greatly appreciated.

Somethings been growing in between and on the plug of my zoa for sometime now, i did a hydrogen dip two weeks ago and that barely seemed to help. Then a coral dip this week and nothing as well. Its almost translucent and looks like very mini tentacles, however it doesn't seem to move. Its grown...

At first I thought the white bulbs were new heads but as it started to take over more of the coral I realized it wasn’t. Anyone able to id what this is or what I should do? I...

My fish suddenly developed white blotches on one of it’s fins an side of it’s face so I have a couple questions. One, what is it? Ich? Lympho? Fungus? I tried to research but a lot of them look the same to me. And two should I treat it immediately or wait? She has a good appetite and I feed a...
