Why is my Helloreef 15g flow so low with AI Axis 40 pump

Any ideas why my flow is no higher than this? It’s a helloreef 15g and the return pump is a AI axis 40 I don’t understand.

Runnning at full speed

Check the impeller maybe?

Dunno if you have a blockage in tube? If you run pump in a bucket, does it blast water or still slow? I have an axis 40 in a 25 gallon and it blasts hard at 70%. So something is def wrong. Might need a cleaning.

Strange. Something is wrong. Disconnect it all and try again? Maybe the flow is leaking out the bottom. If you disconnect and just shoot water straight out the pump is it that weak? That’s another thing to try
