Hi everyone!
My tank is roughly 6mo old and over the past month there has been a good amount of this (See pic) green encrusting algae. I've read that corilline can come in a wide range of colors.
Pic is from my sump but there's a lot of it on my overflow box tool. It's hard like corilline and can't be scraped off with a magna float or my hand.
Any idea on what it is?
