I currently have a juwel rio 240 litre tank that just has the internal juwel filter that came with the tank. I don't feel this is adequate though and would like to get an external canister. So which should I go for?
It seems Fluval FX5 and Eheim are talked about a lot but are there any better ones? I intend on upgrading to a 450 litre in the next year or so would like it to be suitable for that too as don't want to have to upgrade it again. So any idea's?
