Anybody have an opinion on which is better & why? Anybody tried both & found
one to be much better than the other?

I would think the pump fed is easier to set up & is not sensitive to water
levels in the pond but the gravity fed seems to have the advantage of being
able to catch a lot of the cack in a settlement chamber and less pump
maintenance.

I'm trying to decide on which way to go - what's the preference of the
assembled company? All thoughts gratefully recieved.
