Recommend External Filter?

'm currently running a Aqua One Aquis Advance 1250 canister (250L) filter for my 230L tank, it is a bit of a beast, 850L/hr holds 12L of water and is a big 32W, i am very happy with it and was thinking of buying same as back up about £104 i think. but is the Wattage rather high? and can anyone recommend a good large filter that may be suitable?

Thanks WR, i have heard good things about these, i will have to look on the site and see what the L/H  etc is, i think it may be between this and a Eheim of some sort, (but they are very pricey) Is your Fluval noisy at all? that seems to be the only downside.

Thanks, WR, i think the Fluval 406 is looking like the winner, i only have 230L tank and was tempted by the 306 at £89.95 but for the 406 is only an extra £30 so makes sense to get that 

Ah you read the book Sue, i watched the movie, ive already had a look on Youtube 

Thanks Pawel, well it was too small for my main tank but will be great replacement for the 90L, and at £50 for 13 month subcription and free JBL filter, couldn't say no
