Hi anyone know what are these? Hydroids or jellyfish polys. How do I get rid of them please.

I can't see the video but if you're guessing jellyfish it's probably the medusa stage of some type of hydroids. In new tanks they usually go away on their own. If it's a nuisance you can search for colonies of hydroids on the rocks and manually remove. You can also discontinue any powder or liquid foods you may be broadcast feeding and even reduce feedings overall if needed.

Colonial hydroids, I would manually remove as much as I could and discontinue any powder or liquid foods you may be broadcast feeding.

Lower feedings especially suspended matter. If removing by hand- Wear Gloves !! Your best weapon against hydroids is a drug called Fenbendazole (Panacur). It is fish safe but I do not believe coral safe and you should familiarize yourself thoroughly with this drug before using it.
They do sting fish and can result in death. Best recourse to get coral epoxy and smother them with the epoxy which dries to a coraline look. They grow and colonize quickly, so sooner the better
