Default Pond pump speed control

Is is possible to use a speed controller (like a light dimmer) with a small
pond pump?

I have a Bermuda 3000 (3000l/hr) submersible pump that's really a bit more
powerful than I need. The motor has a solid rotor that appears to be made
of a ferrite like material.

I know that speed controllers can cause overheating problems with some
motors but given that it's underwater with water bathing the rotor, I don't
imagine this would be a problem in this case.
