Looking to replace my old Fluval 103 that has soldiered on for almost 10 years now and I am looking for a little advice on what to replace it with. I am not sold on the Fluval 104. I like the XP1 Filstar, but will that be too powerful for a 20 long? Anything from Eheim good for a 20 long? Any help would be appreciated as I have not bought any new equipment in over 6 years, outside of an airpump or 2, and I have 5 tanks of varying size that are going to need filters in the coming year. But for now the pressing need in a canister for a 20 long. Many thanks in advance.
