What Filter For A 120 Litre Tank?

[ShinySideUp]

I have removed the internal filter from my Juwel Lido 120 litre tank and want to use an external filter.

What capacity filter should I buy and does anyone have any recommendations as to manufacturer. The tank sits on a concrete shelf rather than on a stand so there is no room underneath and the filter will have to stand on the floor to one side where I can cover it in with a box therefore the pipe runs will be a little longer than they would normally be.

I use an APS (All Pond Solutions) 1400 lph with UV on my 120ltre tank. Was very reasonably priced new, easy to start as comes with all media & easy to clean and my water is crystal clear. Flow not as powerful as you might think hence ive found this filter ideal but there you go.
