internal or external?

Postby andywroe » Fri Jul 09, 2010 12:00 pm

Looking to replace my 2 x internal juwel jumbo filters in my rio 400 with a eheim externalwould this be a good idea if so which one should i be looking at?

Also is it harder to run or set up etc, and how long should you change the media as the juwel media is costing me a small fortune to replace 2 times the sponges.

Also any other tips on the external filter would be great i.e does it just sit in the cabinet etc?

Thanks Andy

i have always remove the internal filters from jewel tanks it give the fish loads more room probebly the best external you could buy would be a fluval fx5 filter they are easy to run and maintain and yes they sit in the cabinet under the tank and then have pipe that go into your tank from the rear one pipe to take the water out the tank to run through the filter and one return pipe to return the filtered water back into the tank.
they are fairly expensive but worth every penny :handgestures-thumbup:

If you dont mind using gravel, use undergravel filters.
That is what I have in my rio 400. I removed the internal jumbo filter, and now run undergravels and a fluval 405. masses of media, great flitration and crystal clear water. Tank is currently home to about 150 juvie aulonocara about 1.5 inches.

I used the juwel powerheads for the uplifts.

jimbo is right on the undergravel filters they are actually in my popinion the best form of filteration but as he also says it all depends on wether or not you like gravel :handgestures-thumbup:

I am an external filter fan......but if I had the room sump would be my first choice as if its big enough and setup\designed correct you can hold fish in it.

External's for me they have much more media area over internal filters, however internals do have some advantages over externals especially the juwel filters as these are able to skim the waters surface removing the dusting that happens externals dont do this.

I would remove one juwel filter and replace with an external and keep the other juwel in place or even plumb the pipe work from the external into the juwel filter housing using it as a pre-filter and helping hide some of the pipe work.

ok i went out at the weekend and bought the eheim pro II edition very very very cheap :shhh:
Any tips on fitting it going to fit it tomor night, are the easy enough to fit?

What about cycling the filter against the old ones or can i just remove the old ones and replace it with the external?

Thanks Andy.

I would squeeze the sponges from one of the internals into the media in the eheim. and then run the eheim along with the internals for a couple of weeks, before removing one of the internals.
