With all the external filter threads recently i thought it was time we had a pinned review thread.
Please only review external canister filters you own or have owned and please stick to the same format to make the thread easy to read through.
Filter: Eheim ecco 2231
Year of first use: 2002
Condition purchased in: New
Year use ended and reason/s: 2007. Switched to air powered filtration
Likes: None
Dislikes: Self priming handle is fiddly and was broken after around a year. Handle also gets in the way when trying to remove the hoses from the filter body.
Filter: Fluval 303
Year of first use: 2003
Condition purchased in: Used but with new media, gasket and hoses
Year use ended and reason/s: 2004. After around 6 months the filter started to leak, was increasingly difficult to restart after maintainance and suffered from loss of flow even when the media was hardly dirty.
Likes: None
Dislikes: Double taps for disengaging hoses were stiff and difficult to use. Screw clamps on hose tails didn't do up tight and hoses could easily be pulled away from the filter.
Filter: Fluval 304
Year of first use: 2004
Condition purchased in: New
Year use ended and reason/s: 2004. Filter leaked almost from day one, was difficult to restart after maintenance and clogged regularly. In the end i kicked the filter and broke it out of frustration.
Likes: None
Dislikes: Self priming system was a pain rather than any help and the corrugated hoses got blocked up with debris almost daily.
Filter: Eheim Classic 2215
Year of first use: 2005
Condition purchased in: New
Year use ended and reason/s: 2007. Switched to air powered filtration.
Likes: Simple easy to use design. Little loss of flow even when the media was extremely dirty
Dislikes: No self priming.
Filter: Eheim Classic 2217
Year of first use: 2003
Condition purchased in: First one used but three others new since
Year use ended and reason/s: One still in use, others replaced by air powered filtration.
Likes: Easy simple design. Little loss of flow even when the media is extremely dirty.
Dislikes: No self priming
Filter: Rena XP3
Year of first use: 2006
Condition purchased in: New
Year use ended and reason/s: Still in use
Likes: Self priming system actually works
Dislikes: Although the filter appears to have a good flow rate it doesn't seem to have enough "suck" and even tiny particles in the water avoid being pulled into the filter, I find it worrying that after 2 years the media still looks clean and I am sure that the water by-passes the media somehow. The hoses just push onto the hose tails with no screw clamps which in my opinion is a disaster waiting to happen should someone pull the filter or hoses for any reason.
