hello all. just got back from vaction. and my sump is full of hair alge.. my main display if fine. just my sump. any idea what it can be.. i did take all the live sand out of my sump whne i changed it last month.. nothing else diffrent..
i did notice a huge increase in hair algae when I added a pod-eating scotter blenny to my tank. Now that pod populations are back to normal I have not seen any for a while now. Maybe taking out the sand decreased the pods, etc. and nothings there to eat it now... ?
