Question for the experts. So I am now 14 days into my fallow period. Why are my nitrates rising? Starting to see traces of hair algae. I am still doing my regular water changes and only feeding the tank normal dose of reef energy. I understand that the angel and tangs would control the hair algae when they where in the tank but I can understand why my NO3 has climbed from a steady 10ppm to +25. I have increased the time on the fuge light and doing a 20% water change right now. If that doesnt work carbon dose? Also none of the fish died or where lost in the DT so its not coming from dead fish or feeding. So confused. PO4 is steady at 0.02.
