To give a bit of background. I have a juwel fish tank with an in built corner unit filter and pump. Around 2- 3 weeks ago one of my silver sharks went missing, bearing in mind that he is around 10cm long. I blamed this on a tinfoil barb that decided to clear my tank of other fish.

But, i get back from work today and turn the light on and i have again two silver sharks. Not looking in good shape though. Off colour and very scatty. The only thing i can think of is that he got trapped down the side of the filter unit in the corner even though the gap just doesn't seem big enough. I can't understand how the poor little buggers still going, i just hope he fully recovers.

Has anyone replaced a corner unit filter system with an external filter and pump?

Yes.

Juwel Rekord - with corner filter, after some years went by the corner housing came unstuck and fell off (well floated actually).

The tank is now sporting a Fluval 3 internal, heater clamped on by plastic clips. Works a treat and been running in this manner for about 3 years now.

Your silver shark was probably inside the filter - i had a fish dissapear int here, there is actually a fair bit of space under the powerhead/next to the heater, once they find their way in. We found a few 'missing' fish in there over the years (with the aid of a torch!). Like you, we also blamed a number of innocent fish for eating them at one point...

I am also not sure how this topic relates to home cinema mind you...

Hmmmmm i'd cleaned the tank out only a week ago and there was nothing in the filter casing itself. I'm going to eventually fit an external filter and pump. I just can't believe he managed to live that long with out food. I've put some revitaliser tonic in to try and calm it down.

Even the mods are confused with the new layout hehe

Yep, I've taken the corner filter out of my Juwel tank aswell. Very easy to do, and, to be frank, it's better out than in.

You will reclaim some lost volume - which the fish will appreciate.

Also, it saves the release of rubbish back into the tank when you clean the filter out, which, is pretty inevitable. All in all the external filter is the best option open to you

I also use an in-line heater which is very effective at heating water and removes another item of clutter from the tank.

Yep I lost a Royal Gramma in my old jewel Rio 180, I had assumed he had gone carpet surfing down the back, never to be seen again but no, a few says later I spotted him the filter tower(no sponges just a few small pumps) looking very pale, it was a right bugger to get him out, I had to fill the tank to the brim and wait untill he swam out. Poor think perked in the end and is now spending his days happily swimming in the "coral garden" display at Blue Reef in Portsmouth.

My silver sharks still a little scatty and pale but a little better. The thing i can't understand though is that we had cleaned the tank out around a week after he went missing. Took all the filters out and definately wasn't in there. Must have got stuck between the tank and the plastic casing. Just didn't think the gap was big enough for it to get through.

Did it cost much to replace the heater and filter with external units? I don't think the thermostats in perfect condition either, got a mind of it's own sometimes. So i think i might as well replace that also.

I worked in a tropical fish shop for over 5 years and everyone who worked there with a Juwel tank had replaced it with an external filter.

Its very easy to remove the old box (4 lumps of silicon) and you can get to them by just sliding a large knife down the side of the box.

I would thoroughly recommend the eheim professionel II filters, and get the biggest you can afford. They are quieter, better at keeping the tank clean and a lot easier to maintain. With the added benefit of not having to change the Juwel filters every week and month with their schedules. With the eheims it is very much 'fit and forget'.

In the last 3 years of having mine on the tank i think i have only had it open 2 or 3 times.

sorry its taken soo long to get back to this - only just noticed i replied to your topic.....

The price of filters vary, and you should get one that suits a tank bigger than you have to keep the water turning over nicely and have a decent amount of space for media layers. I have a Aqua one cf1000 that cost me about 70 quid in the january sales last year. Its a very good filter in my opinion and works for tanks up to 200l. I picked up the in-line thermo stat at a local shop, can't remember who makes them, but a good shop will stock them.

I agree, eheim are really good but there isn't anyone in my area who sells them and they can be pretty pricey (wanted one of their newer ones with an internal heater but couldn't justify the cost)

Don't know how I missed this post.

What size is your tank? Thats obviouslty going to make a big difference as to which filter you need. Any eheim external will be good, but the pro and pro2 series are very good quality, but as with anything theres different sizes depending on how much power you need. Theres no such thing as too much filtration (a few fish don't like excessive flow, but you can tone that down with things like spray bars and by directing the flow at the sides of the tank.) A good rule of thumb though is you want the filter output (measures in litres per hour) to be 4 times the capacity of the tank, so for my Rio 180 litre, I want a minimum output of 720 lph. (I've actually got closer to 1200 lph mind - like I say, never too much.)

Check out the classified section on TFF - I've been a member for more than a year, and theres the odd bargain to be had on there:

http://www.fishforums.net/index.php?s=57cd88c2ab8f...

And its worth setting up a search on ebay, you'll often be able to pick up a bargain that way.

Let me know what size the tank is and your max budget, and if you're insistant on buying new or used (all my gears been bought used, enough to run and have spares for 8 tanks - never had any issues.)

And bear in mind that once you've put the new filter in place, you'll need to run it for a month before you can remove the old one - or move the mature media into the external filter.

The tank i've got is a rio 125. Budget wise i would be hopefully talking £50 but obviously i'll pay mostly what i need. I always think buy cheap but buy again.

You can easily get a good filter for that money - I've picked up good condition Fluval 4+'s (big but effective internal filter) for anything from £10 to £20.

Are you fussy about getting a new filter? Some people are, but all my fish gear has been bought second hand (though I make a point to only buy those that are in working condition and with all pipework included.)

Something like this would do the job. I do hear of occasional problems with fluval externals but they're usually well known issues that can be easily sorted.

http://cgi.ebay.co.uk/AQUARIUM-FISH-TANK-EXTERNAL-...

On fleabay auctions, theres other options - obviously price could and probably will go up:

http://cgi.ebay.co.uk/Eheim-Professional-2026-Filt...

http://cgi.ebay.co.uk/EHEIM-PROFESSIONAL-2224-EXTE...

http://cgi.ebay.co.uk/fluval-405_W0QQitemZ27038407...

http://cgi.ebay.co.uk/EXTERNAL-AQUARIUM-FILTER-FLU...


Personally I'd be happy with just a fluval 4+, and maybe another filter - a 3+ or a 2+ running in there as a spare. The only thing you might have to do is buy a spray bar if the fish are struggling with the flow. Barring that I'd look for an eheim external. More expensive than other brands of external but more reliable too.
