Looks like GHA, lower your nitrates and phosphates.

I second green hair algae. Need to get your phosphates and/or nitrates down. Start running GFO, do more water changes, start running an algae turf scrubber or even better a combination of all three. While doing one or all of those methods it can also help a lot to reach in there and pull out the algae as often as you can. If it dies in the system it just releases those nutrients back into the water for more algae to use. Removing it helps to remove the nutrients it used to grow.
