Hello, I have had a probelm with red sliem algae on my sand bed in my 5 month old mixed reef. Everything I have read states that this is caused by high levels of phosphates or nitrates. My water quality i sspotless. Nitrates read 0-5 PPM with weekely water changes. I just added a phosban 150 where the phosphate levels were .05 before now read 0! The problem actually started right around the tiem I added the reactor ironically. All levels read good. What else can be the cause???? Any thoughts
