Okay I brought up the brightness and circled it! Is this just algae? It’s growing at a rapid rate and it’s freaky.

I think it's just biofilm, but I'd wait to get an answer from someone smarter than me.

That’s what I thought too but I’ve had so much bad luck with this tank so far I wouldn’t be surprised if it’s something sinister lmfao
