I have an fx5 that is making a lot of noise!!!! It sounds like it is constantly filling with water or trying to fill with water. It purges itself as it should but after it does that it sounds like a waterfall inside the filter quite loud mind you. It does slow down after a couple of hours but then it purges again and it starts all over again. All i can say is that it sounds like it is filling with water all the time or like a waterfall. Water is crystal clear and all levels are perfect so it must be working ok but just making this loud water noise all the time. Has anyone else had this before?? If they have is there anything i can do???? I would appreciate anyones help with this or suggestions. And yes all the connections and fittings are underwater so there should be no air getting in.
Thanks for your help in advance..
