So I got a new 55 gal I’m super excited about. It came with a used fluval 306 canister filter that was full of water and sludge when I got it (so obviously was in use) but I was just super stoked to get such a nice filter along with the price of the tank. I set my tank up and set the filter up. Have no luck with the “primer” so I fill the lines with water myself and get it flowing. I plug it in and... WATER EVERYWHERE. The lid seems to be on securely and the o ring seems to be in good shape. However, water was not dripping, but actually spraying out of the side near the locks, and running down the back. When the lid is on securely the locks seem very loose. Also, there is dripping from the sides of the valves at the top where the intake and outtake lines connect. Is this filter too far gone? Should I buy a new one or is there any idea how this one may be fixed?
