What algae is on my snails shell?

Anyone know?

Anyone know?

I don’t know the true difference between the two because they’re so similar but it’s either turf algae or green hair algae. I’ve got the exact same looking stuff in one of my tanks and it’s a nightmare because the surface is so adhesive.

Looks like GHA. Toothbrush the shells (outside of the tank). I usually do it in the water I take out during a wc when I need to.
