Hey guys so I just setup a smaller Peninsula tank to compliment my Fusion Pro 2 30L. Problem is the 326 GPH Mighty Jet return pump is making the worst droning, or humming sound that seems to get amplified through the cabinet I built. I can hear it across the house when it is quiet and when I put my ear up to the glass it is extremely loud... I am a little worried about going forth and stocking this tank if it is going to bother the fish. The pump itself is sitting on a silicone mat, connected to the elbow joint with silicone tubing... however if I put my hand on the acrylic divider wall it is vibrating intensely where the elbow joint goes through and into the DT. I am not sure if it's where it it making that connection with the acrylic wall but it feels like it or if the pump is just loud as hell because of the tiny chamber it Barely fits into. I see alot of posts online about it bit they are all addressed at fixing the issue which I will try.. I don't know how but will keep trying different methods. However MY main concern is the fish being in that environment and also the integrity of the seals until I can get it figured out. The picture is of the small return chamber... and that elbow feels like it is the main source of vibration... any ideas?
