Red macroalgae

Can anyone ID this covering my rock? It spreads so fast and has taken over my scape. Any ideas for eradication?

some sort of gelidium possibly? I had an issue with a very similar looking strain that i was able to reduce with a 3 day light out, manual removal and nutrient control. After that i added a mexican turbo snail and he mowed the remainder down.

I was hoping to avoid a blackout but it might inevitable. I started broadcast dosing peroxide today to help with chrysophtes. Hopefully that kills this crap. It’s sps dominate

I’ve finally ID’d this as Asparagopsis taxiformis. Anyone ever successfully beat this stuff back?

Just wanted to update this for anyone following or using the search function in the future. I dosed Reef Flux (fluconazole) and it is slowly killing this stuff. Asparagopsis is the worst algae I've had to deal with in my reefing career thus far and I'm ecstatic Reef Flux works against it. Manual removal and h202 soaking each rock was not feasible without a total restart.
