60l Tank What Filter?

[stevo_gti]

i have a small 60L tank running with few tropical fish in and want to upgrade to a bigger filter its currently running a clearview 280 hang on back and a undergravel filter, the tank is an aqua one horizon 60 so its not got a cabinet for an external but im thinking if i take a shelf out the stand i could possibly get one in there also thinking about just getting a clearview 500 they are rated for tanks upto 120L plus it will fit in the same place as the old clearview one

any other filters you would recomend would be great.

thanks. mark
