Looks like your typical blue/green algae that comes with SW tanks.

Well it's not bad if you keep it under control, No3, Po4 and CUC. If you keep the nutrient down and get a good CUC, you'll be fine!

More neutral..... it's not GOOD great will help tank algae, but also isnt bad take it all over and kill stuffs algae. Kinda just part of a tank growing up.
