Trickling water noise

[HarryH72]

Hi I have a neptunian cube m pro 90 which I have recently done a water change one and replaced the filter socks. Since doing so I have a constant trickling water noise coming from the filter socks in the sump. It’s driving me mental but can’t seem t eleviate it. I’ve tried adjusting the flow rate into the sump, return pump speed but all to no avail. I took water out of the tank and no change, have I not got enough water in?

The bottom of the socks might be above the waterline in the sump.

Check how the filter sock is seated. I don’t use socks but I use a plastic cup which holds filter floss and rock. My “cup” will leak around the plastic rim and the dripping into the water outside of the filter sock will create a noise you are describing.
