Are these copepods?

I’m seeing many of these white dot/lines on my reef tank acrylic. They move fairly quickly and scrape off with my algae scraper. I added copepods a month ago - but want to confirm that’s what these are as opposed to something harmful!

Can someone please help ID?

As far as I can see, a mix of copepods and Isopods (the good ones)
