How does your substrate look?
In case you haven't been told, newer aquariums go through a series of algae phases, which include things like diatoms (good, normal, food for bacteria), cyanobacteria (normal, undesirable, can be frustrating to remove), detritus (normal, made up of fish waste or decaying food), or lastly dinoflagellates (awful, something you'll never want to deal with).
