coral bleaching

I turned off the lights for three days for algae issues after 3 days one of my corals turned white color like the picture attached

That isn't bleached. Bleached means the polyps are transparent and white ish. That's just a skeleton, meaning it's dead.

I agree with @Spare time. Sadly, that coral died.
Bleached coral *usually* come from too much light causing the zooxanthellae to bail out and the coral turns white or polyps/tentacles turn clear.

If it was a euphyllia, I usually keep the skeletons in the tank. I've had a number of them start to come back after a few months to a year.

So should I remove it from the tank?

It's basically just live rock at this point so it's up to you

Yep, it's dead. Sometimes euphyllia can grow back from skeleton but that's usually just hammers
