I have read a number of threads over the last few days all having a go
at any Juwel internal filter. I except that a large external is a good
thing but I am looking at the least amount of clutter I can as "the
other half" is more than keen to stop me having a tank at all if it
looks too messy.
They seem to use a bit too much sponge for my liking rather than good
solid bio friendly filter stuff like Biomax. Is sponge any good for a
biofilter material?
Having looked at some diagrams I have noticed the Juwelfilters seem
tohave a large number of slots at the base of thier body, does this not
bring in water allowing itto bypass the filter media?
I do have an oldspare Marathon 400 external which I am looking to add
in as extra filter if I have to, do you think I can hook up the output
of the internal filter to the input of the external?

Your other half uses too much sponge? ;)

It has to bring the water in from somewhere... water flow goes through the
slots in the bottom and out of the powerhead at the top.
All internal filters work in the same way - course sponge at the bottom,
fine sponge / wool at the top... they're not big enough for other media such
as ceramic rings.
If you've read nothing but bad things about Juwel filters, why are you
considering getting one? Look at the fluval / eheim range of interal filters
instead.

The flow rate wouldn't be the same, so it's not a Good Idea... but why would
you want to anyway?
The two filters would be more effective independantly, and provide you with
a backup if one fails.
Unless the Juwel is a real beast, the marathon external (even though it's
not particularly good) will do a better job and will be easier to
maintain... when you come to clear out the fluval there'll be a cloud of
crap floating around your tank.
I'd go with just the marathon and buy a pretty pink floral tablecloth to
hide it behind.
Given the price of a good internal filter, why not instead use the money to
buy a decent looking cabinet to accommodate the tank and all your
paraphernalia?
I've had a few tanks & cabinets from www.freecycle.org - chances are there's
a group in your area... local papers are good too... it doesn't have to be
new & expensive to look good.

Well it works, what more is there? I've no doubt a good external filter
would be better, but the juwel system works.

Side not base, I would need to open to check but I think its just an
alternative water input and doesn't bypass anything. The pump pulls from
the middle of the flter stack, and the bottom, so the higher mechanical
sponges get a higher flow rate than the lower biological ones.

I think you would struggle to get a seal, and wouldn't get the flow right.
You could conseal the tubes from the external inside the excess room inside
the juwel filter, but this may mess with the flow inside the internal one.

I've got a Juwel filter and it really does a good job. I like the way the
heater is concealed within the tower, and in my aquarium you really don't
notice the tower as plant growth is rapid.
Bottom the loower side grill and higher front grill draw water in, and the
variable direction of the outlet means you can create a variety of curren
effects. My 2p worth.
