I redid my aquarium recently. I changed the substrate, drilled it and fixed the top. Anyhow, I have a ton of algae now. It is a 220 gallon, with 8 96 watt (I think 96 watt) 6700k T5 flourescents. 4 bulbs are on for 2 hours, 8 bulbs for 8 hours, and 4 bulbs for 2 hours. I am sure it is excess nutrients, but I am not adding anything. I have even turned off the CO2. Please help. Here is a video. I just got these royal blue uatuma discus.
