I added more water and the filter is running better - but it is definitely not running at 400 GPH. I'm sure putting the extension tube on the filter would help, but if I did it would basically be sucking up gravel as my tank is not too high.
Could I somehow cut the extension tube, so that it can go lower in the tank, but still fit?
I cut mine down a bit with a hacksaw. Burrs can be lightly landed to smooth them down. However if you have low water in the tank I'm not sure adding additional tubing will help your issue much. I'm sure others will chime in on that. Posted via Mobile Device
