i only plan on using a 550 gph pump for now, but in the mean time
will a smaller pump running on a bigger bioforce pressurized pond
filter cause any harm?

Bump. I don't think it would. If this is a bead type filter, it may not
move the beads at optimum. Thus they may clump. ~ jan

When it's in filter mode the beads need to clump, otherwise how would
they filter anything :-)

It's only in backflush mode that the beads need to 'unclump' and move
around.

Bead filters are not intended for mechanical filtration - they're
biological, which means you need the maximum surface area exposed to water,
and you don't want them clumping.
