Hi, I'm looking at adding an external canister filter to my 120L tank. I have the built in juwel internal filter atm but would like to eventually replace this with an external to free up space and improve the look of the tank. The problem I'm having is that all good canister filters seem to be really tall and the space I have for it is only 33cm/13inch tall. Can anyone recommend a good filter that would fit? I would like as many lph as possible. I really liked the look of the all pond solutions ef/ef+ range but looks like they will all be too tall. Any ideas?
