LOL I'm all over the place! I've read & read about the external
pumps, priming pots, leaf traps, etc. I have a few reservations and
am more leaning to the point of not spending the time to create the
housing, etc. required.

The hose from the pump in the pond will have to travel at least 4 feet
high and 4 feet long. I'm going to use flexible hose so there
shouldn't be any elbows.

So if I get a 750 gph pump just for the biofilter - wouldn't by the
time it got to the source then had to deal with the biofilter -
wouldn't the actual numbers on the 750 gph be greatly reduced? I.e.;
wouldn't I end up spitting out more like 400 gph by the time it spills
out the biofilter?

I'm just ready to make an online purchase and am concerned about what
size to go with that will do the trick to keep a clear pond year
round. I won't have much opportunity to have plants.

Sorry if I'm being a pain, but I appreciate the help.

If you step up your hose to 1 1/4 or 1.5 inch (one fitting) from the 1
in output
you shouldnt loose very much in only 4 feet rough calculation drop to
735 gph if even that much remember you only calulate head from pond
water level to hose output there will be so very litle loss in the
hose from the pump[ to water level its incalculatable exept by a physics
major

If it can't be fixed with bailing wire or duct tape
its not worth fixing
