Reef sumps by ESHOPPS

I have not seen that one, but I'm not a big fan of premade
sumps with baffles. I much prefer a regular tank that can
always be used as a tank later, and can be flexible in
use. I prefer to use live rock, and sea weed instead of
baffles. And instead of drilling a sump, I prefer to use
an external pump, and simply send the plumbing up and over
the wall of the tank.

Anybody here using reef sumps made by ESHOPPS ?
Here is the link: http://www.eshopps.com/reefsump.php

I saw them yesterday in a local pet store, they
are quite expensive: RS-200 is about $200...

I was wondering if they are good and if they can
be purchased somewhere online little bit cheaper.

Over the wall of the sump that is.

Using seaweed requires the sump to be lighted.

Not using baffles you are dealing with air bubbles
going into the return pump and geting into the tank.
How do you deal with air bubbles?

Also, occupying sump with live rock you have no room
there left for placing skimmer, phosphate reaktor
and other devices people normally put in the sump.

Having 90' elbows on your plumbing you waste the
pump power - each elbow is like a foot hight, so
the flow rate you get from the pump is much lesser...
I also do not drill the sump, but I use internal pump
like quiet one 3000 which has enough flow for my 58 g.

Yep, and many people are liking the benefits that
refugiums provide.

Live rock rubble in the sump takes all the bubbles out.

I have room for a 1,000 gph protein skimmer in my sump,
and room for carbon and any other bags of media I may want
in there, currently experimenting with a bag of sulfur.

I use 2" thin wall pvc pipe.

I like external pumps because when the electricity comes
on they kick on, as they are real motors, and not vibrator
pumps. Also less heat transfer.

Refugium and lighted sumps are not the same thing...
If you have high water flow than it is not refugium
anymore - all the plankton will be swept away to the
pump or the sponge on the way to the pump.

Do you have any drawing you could share to ilustrate
the way you design your sumps?

I find the bags in the sump very inefficient solution.
Water finds its way around the media bag and does not
penetrate carbon correctly.

Do not experience problems with starting of my pump.
Power outages are quire frequent in my area.
Powerheads like quiet one 3000 give you more water
movement per watt of electricity than external pumps.

It's still a refugium for algae, and pods, but yea there
are other things that won't stay in there with strong
water, but a larger sump with space for slow water will work.

Ok, I just got some pictures up of the third cement tank.
I need to get more up, but, here's some pictures of the sump.

After a while just like powerheads, they start to wear,
and don't want to start back up. The pump I use will start
to squeal from the wearing of the bearings, first
chirping, and then longer to becoming squeals, long before
it fails from wear.

Yes, that's correct. Because of their design, they will
use less electricity. External motors don't use the
vibrator pump method, but are actual motors that continue
to move the shaft in the same direction until it gets into
the next position, and then the next electrical contact is
made, forcing it into the next position, and so on, and so
they use more electricity.

What the heck is the "vibrator pump" method? I'd say your concept of how an
AC motor works is a bit weird. There is really nothing inherently more
efficient about a magnetically coupled, sealed, pump over what you are
calling an external pump. Every power head I've ever seen uses a sealed
rotating magnetic field which couples to a magnet attached to the impeller
shaft. What you are calling an external motor works in almost the same way,
a rotating magnetic field couples magnetically to a rotating shaft which is
then coupled mechanically to an impeller. The only advantage I see in a pump
mounted external to the sump is that it won't transfer heat to the tank.

The difference is that a submersible pump like a powerhead
works by giving an alternating magnetic charge. You will
notice that when a powerhead starts up, it's a 50/50
chance as to which way it will spin, and if something gets
stuck in there, like if you stick your finger on the
impeller, you will notice that the impeller vibrates back
and forth.

But a external pump like little giant, uses windings that
are charged in order one after another, depending on the
position that the shaft is in, because the electrical
contacts on the shaft control the polarity of the
electrical field being generated.
