I just purchased a used 100 Gal tank. We moved the tank 2 weeks ago, and the Refuge is not growing. I have minimal Ammonia, Nitrite, and Nitrate is 0.2 PPM. I noticed that there was a growth on the refuge, it looked like hair algae. I added a 300 GPH circulation pump in the refuge sump because it sank to the bottom and did not move. There is a light on the refuge for 18hpd.
Is this loos of refuge just due to low nitrate levels?
