What Algae is this? it poped up all over my rock's on the light surfaces just after my Tank had completed cycling.

It’s part of the cycling period. www he key is to make sure it doesn’t turn into a full blown outbreak but that algae with good levels will turn to coraline algae in time. Get yourself a good cleaner crew to keep the wispy hairy algae in check
