looks like its for air bubbles, etcwhat do i need to do with it, hook it up with, etc?thanks all
Just stand behind your tank and slowly blow air into the tube. The bubble effects will be amazing and your fish will appreciate you.
That's there so you can hook it to an air pump and make it bubble if you wish. MM
You need an air pump and a bit of silicone air line tubing.
if you have a filter with an air pump you can buy an attachment to divide the air output. if not you can buy a very small air pump for under 10 dollars at most petstores or walmart.
