Mr. Graham,

A lot of this is going to depend on the application. For example, a Rainbow
Lifeguard Quiet One is a fantastic recirculating pump, however, if you put
any kind of a head on it, they're nearly worthless and run REALLY hot
(wasting energy which costs something). Conversely, an Iwaki 70 RT for a
recirculating pump is absolute overkill in power and investment.

A good general pump that I like are the Won Brother's Sen pumps. I like
their flexibility in application (you can use flex, hard plumb, submerged,
unsubmerged) and you can not beat the price for the power you're getting.
They run *very* efficiently compared to any other submergible pump I've
played with, and you don't have the priming issues that are commonly
encountered with the Mag Drive pumps. The 17' power cord is a serious bonus

Here's a little ditty a good friend of mine, and hopefully soon fellow
NANFAn (he's joining the list now, thanks Jim ;), Shane Graber put together
for Reefs.Org:

You can compare the performance of the pumps and then evaluate by price.
Look, for example, at the Won Brothers Sen 900 and a Little Giant 3 MDQX-SC
and compare their performance. Then go online and compare prices. Beyond
that, compare the flexibility of application the Sen offers. Wow, it does
the same, Ol' Todd can vouch that it runs waaay less hot (ie more
efficiently) and it's 300x more flexible for considerably less money!? :)

If I *had* to hardline in an external pump, I'd go with an Iwaki or Dolphin
pump. But I try to avoid those kinds of projects these days :)

For inexpensive 75 gal or less in-tank circulation (like drag and drop) I
like the Aquarium Systems MaxiJet 900 or 1200. They're quite reliable, and
you can aim them any direction. I like to point them to the water's surface
and allow them to "pull" the entire water column, as opposed to making a
whole big mess with velocity.

I also do this with Ehiem canisters... But one would need to be willing to
part with the money for that type of application.

Of course, if someone were selling *any* pump for super cheap, well then
it's worth considering at least :)

Hopefully Shane will have some extra thoughts, as he's been watching the
development of the technology since I bowed out. There are a couple
different circulation options that exist now that are very very powerful and
inexpensive... I'm just not all that familiar with them.
