I have just noticed that I can see the 2 coloured wires showing through on my tank pump where the black cable is connected as f its been pulled.. I have a swimming area for my water dragon it is 2.

If you don't, the filter will pull in air instead. Keep an eye on how much water is in your aquarium—most filters need the water level to be about one inch from the lip of the filter. If bubbles go up the main tube, it will cause a rattling sound and may stop your filter from working.
