Hello Rodney

RP Below is a rough guide on rating a pump.

Useful stuff.

RP I don't know the Nautilus 30 (I'm in the UK) but the
RP Nautilus 3000 would only be pumping 56gph at this height,
RP 385gph at 6 foot so if these are the same pump then no, it
RP won't manage. Look at something like the Otter Maximus 5000,

Price for the higher power pumps seem to rise dramatically though.
I've used twin smaller pumps (200watt general purpose submersibles,
not something badged as "pond" because that seems to put the price up
for no particular reason) to gain an equivalent output for less than a
single big pump. Gives an advantage in that if one does break and the
pump is producing oxygen, you don't have to panic to get another in
before all the fish die.

Just a thought.
