Man my tank had a super algae outbreak at the start, grew into a forest. Then I threw a foxface in there and didn't feed him for two weeks, ate it all. Just let it run, it's going to get ugly. Keep testing about wait for the ammonia/nitrate spike then they'll work down to around zero and you'll be good to go. Patience is key, took my tank 4 months to cycle.
