Adding An Extra Filter To My Main Tank

Hi everyone,

I've been thinking about adding a second filter to my main tanK – Juwel Rio 180.
I'm thinking of the Allpond Solutions Aquarium filter 700LF all in one with UV steriliser (for tanks up to 150 litres). Or, the Allpond solutions internal 800LF (no UV steriliser, for tanks up to 150 litres).

The reason for this is to give extra filter capacity, and to have spare media for QT tanks etc. should the need arise. I don't want to overstock my tank at all, but I think that having the extra filtration will be beneficial for the fish. I don't want to go for an external filter because I'm not at all handy with that kind of thing.

My questions are:
1. Would either of these filters do the job, or are they too big?
2. Would it be beneficial to have the one with the UV steriliser?
3. Where in the tank would I position the extra filter? I have several surface-dwelling fish and don't want them blasted from one side to the other or caught in a cross current. Would it therefore be better to have the filters quite near each other rather than at opposite ends of the tank?
4. Would I be better with a smaller filter so as not to cause too much water disturbance for the fish?

Any advice welcome,


Diz
 

Thanks Sue,
And where would you situate it in the tank so as not to blast my surface-dwellers about, which I'm concerned might happen if the filters are at opposite ends?

Brilliant Richard W, that's what I'll do then!
