I will start out by saying that I have not tested the water parameters and have no idea what they currently are. I suspect that they are low based upon coral growth and polyp extension. Nothing is suffering or looking at all impacted by the cyano. My suspicion is that the biopellets are fueling the cyano and that if I take the reactor offline the cyano will begin to disappear. Is this a common problem? Last time I had problems with cyano I suspected the biopellets, but I have not removed the reactor. The effluent from the reactor is flowing into the intake for the skimmer as it should be. The skimmer has always been challenging to adjust though. What do you guys think? If I pull the biopellets do I need to worry about other problems?
