upgrade to an external pump?

looking at the Pond Mag Drive 18 - 1800 GPH (Supreme) from that pet
place, whats a good bottom drain, skimmer and leaf trap to buy?

iirc, that's not strictly an external pump. It can be used out-of-pond, but
it is submersible. They're good pumps, but the advantage of going external
is energy efficiency, and a Sequence is much more efficient than a Mag. If
you're going to use the mag, I'd still drop it in the pond. I like
submersibles.

Looks like i need to learn a few things
sorry if these are stupid questions:

whats a Sequence?
I was looking at external for ease of cleaning and mag for low power.
Whats the advantage on having it IN the pond?

Brand of pump. I like them.

Mag does not imply low power. Mags advantage is no shaft seal to leak.
Since I've never had a shaft seal leak this is not a big advantage IMHO.

Out of sight (maybe), simpler (or no) plumbing.

Disadvantages are oil leaks, shock hazard, takes up pond space.
And if your filter is in there with it, tough to clean.

Andrew's said everything I would have said about the pros & cons of in-pond,
except noise. Now, I've never used an external pump - my last pond was
quite big enough not to worry about the space it took - but external pumps
are pretty well guaranteed to be noisier than submerged pumps. Sequence's
are supposed to be pretty quiet, though.

The plumbing for in-pond pumps _should_ be simpler. I let my wife talk me
into having "professionals" build my waterfall (I suspect she - rightly -
didn't trust my artistic side). I had an in-pond pump, and the morons ran
the plumbing _out_ of the pond, then up through the bottom of the head-pond
for the waterfall. It used twice as much plumbing, and always leaked a
bit, compared to running the pipe inside the liner but under the waterfall.

Ok,
I want to get the lowest power usage external pump I can thats
appropriate for a pond of my size. any suggestions?

I have a big ole Sequence 7200 and it is pretty darn quiet! It certainly
cannot be heard over the waterfall and it uses only 500 watts, but pumps a
ton of water. I bought at azponds.com - they were recommended by Sequence
as being the cheapest.
