That looks alot thicker and longer than whats in my tank. The algae in my tank is growing mainly on the live rock and glass. It like a thin coating of it

This one i guess looks like dino...
If it is? water change for few days 20-30% at a time and less light..You also have to disturb those algae and siphon it.. That works for me, the cause was Zeovit overdose...Hope this help..
