Too small for a koi or two?
They wouldn't be happy, and if you want primarily a plant pond you won't be
either - they make a mess of plants. Get goldfish.

Should water turn-over be 2-3 times an hour as some sites suggest
(that's a lot of water to move)?
Mine turns over once an hour (4000-5000 gallons) IMHO, turn over rate can be
less for a larger pond.

Why are there not any pond pump head calculators out there? Can I just
not find them?
Head loss is really specific to the manufacturer of the pump. Go to their
web sites and most will give a graphic illustration of head loss.


Hope that helps
