hi,
had my tank set up for just over a week now, but something has been bugging me since I set it up. The filter/heater box in the tank has two compartments, one for the filter medium and one for the heater, they are connected via the tube that the powerhead connects to, now the thing is that the diagrams that tell me how to set it up CLEARLY states that the coarse medium goes in first then as the layers of medium rise through to the top of the compartment the medium gets progressively finer until the top and last layer which is the poly pad, ok you think? But the powerhead pulls water down through the filter medium compartment and up through the heater compartment.... ok? this means that water is pulled first through the poly pad and down through the layers to the coarse medium at the bottom, surely this is working backwards, at least since I've been fishkeeping (5/6 years, with a 5/6 break until now)filters have worked the other way. Have things changed? Does it matter? Or is this a misprint in the instructions?
Any comments are readily welcomed.
Thanks Darren.

im with you RD doesnt make sense to me thats why everyone i know remove the built in filters + replace em! they also take up too much room in the tank for my liking they're easy to get out as they're only glued in with a couple blobs of sealant
04-09-2006
13:12 by FISHY
why what whould you replace with?? i relly like em everything neatly away and they take up no room realy.
04-09-2006
13:13 by paul stevens
I done the same took them out and put separate ones in cant beat it.
04-09-2006
13:17 by telboy
fishy all the built in filters ive come across take up about a third of the tank space and they look horrible
04-09-2006
13:17 by FISHY
iv bin thinking of an external filter. but apart from putting in an external one noway whould i replace them.
04-09-2006
13:18 by FISHY

Every one to there own i suppose.
04-09-2006
13:21 by telboy
also i found em a nightmare to clean out!ya take out the sponges + all the muck goes back into the water but hey each to there own!
04-09-2006
13:22 by FISHY
yer. again i find them so easy to clean just lift out 2 baskets, how could it be harder?
04-09-2006
13:26 by paul stevens
Yeah but we could say the same about a fluval.

I have 2 RIO 125's, I dont touch my filters for 6 weeks, Just regular water changes, I find that internal jewel filters never lose pressure even when left for 6 weeks....

There good filters and suit the tanks there built into!
04-09-2006
13:39 by FISHY
i agree
04-09-2006
13:44 by FISHY
i have a fluval in another tank and to be honest i think its rubbish compared to the juwel
04-09-2006
13:45 by FISHY
they look so ugly too
04-09-2006
13:51 by FISHY
the juwel filters look v v smart just a small black box in one corner. and thats it.
heater, pump, all wires hidden GONE. unlike the ugly fluval ones were you see the wire too. then you have to add your heater and see another wire.

No, the fine blue sponge then the coarse then carbon (if you want it) then the poly pad. Water is pulled throughthe top and side, the last sponge it hits is the fine thus trapping the smallest paticles that were missed by the other sponges.
In my filter i have ceramic media in a bag at the bottom, one fine sponge, 2 coarse, no carbon, nitrasafe bag and filter wool. Don't buy the expensive poly pads, buy a cheap bag of filter wool instead, mine was £4.99 for 5 metres.

These internal filters, along with most other types, do not hold enough or suitable media to fully support a good bacteriological growth.
Coupled with the rqeuirement to regulary clean them, the bacteria does not get a good foothold.

They may be OK for the smaller community tanks with a few small fish in them but for anything larger than 4 foot, an external has got to be the way to go

i clean out every filter pad every month in used tank water.
done this for 5 years in 2 juwel tanks. never never had a problem with them.
04-09-2006
14:53 by FISHY
VON,"nitrasafe bag" are they any good??
thanx
04-09-2006
15:08 by wymcot
Fishy, get an external and you'll only need to clean it every six months, depending on bioload.

If its working for you, then OK, what I'm trying to say is that externals are far better than internals
04-09-2006
15:35 by von
I have both on my tank, the juwel jumbo and a fluval 404, as for the nitrasafe, to be honest i forget to take it out and recharge it. I do my water changes reliously once a week so i don't really have nitrate problems anyway
04-09-2006
16:35 by FISHY
yer if i was to change it whould defo be for an external (which i am thinking about) but as for internal filters juwel all the way.
04-09-2006
16:44 by wymcot
Fishy- you possibly correct there as they hold far mor media that most other internals I'm aware of
04-09-2006

internal jewels are basically quite poor, its well known, and generally when i discuss Juwel tanks most people (but not all obviously!!!) they agree. To this day i still dont know anyone with a Juwel 180 or bigger that hasnt needed to supplement the original Juwel filter.

I would be happy to advise anyone that any Juwel tank of 180 litres over has a filter that is just VERY BASIC and will do the job only if you half-stock the tank

Poor filters whose powerheads often seem to lose power after year even with cleaning.

SONIA. i totaly disagre and mine is on a very well stoked 4foot tank!!
04-09-2006
18:43 by sonia
thats cool fishy its only my experience and i only know about 5-6 people with big juwel tanks but most people on forums tend to agree, but I am sure they must have some satisfied customers
04-09-2006
21:40 by FISHY
ok
all i can say is personaly i can not fault them
04-09-2006
22:09 by jaystar
i have the rio 240..i like the filter in it but i did add a ehiem 2224 aswell,those common plecs poooooo too much and wife over feeding them
05-09-2006
12:11 by RedDarren
But my point was will the filter work ok like this? dont really want to change it now but dont want to make any comprimises with my tank.
