Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin

I read somewhere that you can modify it to make it more effective but forgot the link; but rly would just replacing it altogether be less hassle?
your thoughts pls guys; are there any who swears by it?

Read the virtual idiot proof guidelines in your manual and you'll not go wrong. Having said that, leave out the carbon sponge as its a waste of money under normal circumstances.

Otherwise, for the paltry voltage they use, you have a second filter if you add an external aswell so if one lets you down, I have forgotten to plug one back in and the media died so the internal saved me a whole lot of trouble.
I personally don't like 1000s of cash depending on 1 plug and 1 filter. If a filter fails, your are still good to go and this can happen, no harm in a bit of redundancy if it is not too unsightly.

If you change the poly pad (at the top) every week or so, the rest of the sponges underneath will remain relatively clean and then will require minimum maintenance to avoid clogging.

Yes, my point, this is far more regular maint than a cannister. But because I have an external too I dont have to clean the poly every week, no flake in this tank all sinking food, floating flake goes right to the internal juwel filter, so I only gotta clean it once a month, cannister almost 3 months.

No need to answer as I can see it's a one way conversation.

IMO they leave a Tank devoid of balance and take up too much space, they also provide Dead spots in the Tank for all types of goodies to hide out. Try chasing any wayward fry out from behind one, they require the lid to be removed to access the partitions and I could go on.
But if you LOVE them , here's a link for all you Juwell lovers forum.bidka.org/showthread.php?t=2049
Kev.
It is not essential to leave the lid on and it takes seconds to access the trays anyway so I don't see the problem. Also for fry to find a safe haven, well, that can't be a bad thing.

minus points- not powerful enough; takes up space; requires more clean definitely;food tends to be sucked in;unsightly; etc...
plus points- cheap to run/low voltage and and err
well to be honest it does sound powerful with all the different media inside; mine have the full package except the carbon which i took out after recycling. however i think any external cannister shld do the same job.
i do 2 20% water changes per week but still find many white specks; 'dust' floating around which really drives me nuts!!! -largely thanks to you guys who always parade a 'spotless' picture/video of your aquariums

anyways thanks for opinions and links guys; hmm let me have a look at the jbl cristalprofi e1500 which come with a UV-C water clarifier again in zooplus..
(ps will i need the UVC for my freshwater? have to pay another 30 odd euros for it)

I find them fiddly to deal with (even an internal is easier to take out, maintain and return) and nowhere near as effective as an anverage external.

However,I've probably answered the same question several times.
In my experience,the Juwel internal filter is more than adequate if you follow the recommended stocking and maintenance guidelines.In comparison to other internal filters,it has a massive media capacity,with a slowish water circulation through it,which makes it quite effective.
However,if you want to knock up your stocking levels,and arn't too good at doing your water changes,then you may want to remove it and replace it with a good external,NOT another internal.
This is based on my experience with smallish Juwel tanks,up to 180ltrs.I would reckon the bigger tanks wouldnt be as effective.
always on the lookout for interesting corys.pm me if you know off any!
