SOMEBODY PLEASE HELP!!!!

Has anyone seen this type of 'algae' before?! I have tried lights out for 2 days, ChemiClean, water changes, etc... It's killing stuff in my tank... It's the brown spider web looking stuff, hard to see in the video but there is a covering on just about all the rocks. It almost goes away on lights out, but as soon as the lights come back on BOOM it's back. I have been battling this stuff for months now. Killed Pearl Berry, and working on my Birds Nest now...

Look into dinoflagellates. That is more than likely what it is. Good luck...

Can't really see anything in your video. Sounds like dinoflagellates from your description. Its probably not actually killing anything itself. Things are probably dying for some other reason and its just taking over. How old is the tank? Have you changed anything or are you missing any fish or snails? Have you tested for nitrates/phosphates yet? How are your other parameters.

The coral are dying because the stuff catches on them in the current and it stays and buggs the crap out of it till the polyp recession ends in death. I'm not missing fish for sure. Snails, haven't counted them, don't know how many I have in there any how. The tank is just over a year old.

Po4 - undetectable Hanna (not ULR)

It's dino. Try slowly raising the ph to 8.6 and blackout for 4 days with no water changes. That's how I got rid of it I also used peroxide. I got it from a frag and it smothered and killed my fire and ice before I realized I had it.
It's a tough battle. I noticed most of your corals are still small on plugs if you have a quarantine tank to move them to you could do a longer blackout and be sure. No half measures with dinoflagellates it's caused a lot of people to leave the hobby or completely tear down their system

Is it worth dipping my coral before I put them in QT? I've never dipped anything so advise is VERY welcome.

Yeah I peroxide dip all my corals 50/50 for a couple mins. I don't have sps so not sure how they'd react but most softies seem to like it I've had zoa's that hadn't opened in weeks do to the dino after a dip they were back open the next day and multiplying soon after. All it takes is one issue and then nothing never gets plopped in again.
One of my lfs has bad flatworms I'm sure a lot of people are cussing them about now
