Can someone help me ID this worm-looking critter that I found in my new Pond Ecosphere?

Hi all, I'm doing a school project on improving air quality, and I've read that autotrophic microalgaes improve this. I don't know a lot about jarrariums, but are there any algaes that are beneficial to plants and other organisms typically in jarraiums that don't need to be cleaned out?
