I would assume your filter is a cartridge type, and if so, yes you can
use it for pond use, either for particulate or biological purposes.
For mechanical, simply get a new cartridge with a larger micron rating
so it doesn't clog to fast, I would suggest getting a couple so you
can change them for cleaning. When one gets to loaded, simply change
them out, cleaning the old with TSP (rinse thoroughly). If you want it
for bio-filtering, get a length of PVC, ABS or whatever you can find
that closely matches the core of the old filter cartridge, drill a
multitude of holes in it, install it in place of the cartridge and
fill the void with your favorite flavor of media.. The pump should be
throttled down at the output side of things and can be done with the
addition of a gate valve in the line. A ball valve is acceptable, but
gate valves are more precisely controlled.
