Hi friends,
I've bought a second hand filter to set up a turtle tank.
It's all in place, but the filter won't work. It's an Aqua One Nautilus 2700. It will work for 4-5 minutes and then the water stops flowing and the knocking sound begins. I'm on day three of trying to get this thing going.
Do I just give up and buy a new one?
Or - is there a company you know of that offers help setting these things up?
Any suggestions welcome.
