I bought two ehiem 1260's for my return flow, which is too much flow. So I just have one running and it is really loud were the water returns to the sump. I have pvc coming off the bulkheads to just below the water line in the sump, what else can I do?
another question if I turn the 1260's on and off once a day is this going to were them down?
