Help! not an emergency

[new but handy]

Hey does anyone know why my durso drains water level went up above the vent hole and is making the loudest sucking sound ever. I know why it's making the noise but is it clogged or what

[mark]

Have you changed the amount of flow (new pump), check to see if there's any blockage (salt creep etc), if not may need a little more tuning.
