Hi, I got a marineland pillar for Christmas and followed the directions for tank and filter setup. I filled the tank with water, put the filter in and added some water to the filter then plugged it in, but while the filter is making a lot of noise the water is not flowing from the filter in to the tank. I tried taking it apart and making sure the impeller is fully in the housing then plugging it in again but after 5 minutes of running there is still no flow, just a lot of noise. My other tank doesn't have a filter so this is the first one I've set up in quite some time. Any tips/suggestions to get it working would be appreciated.
