This is refreshing and odd for me to read, a forum where filters can be discussed without it turning into the Eheim fan club doing their best to bash Fluval externals
.
I'd vote for the 105 too, I run one on ~60L of water and it's excellent. The tank only has shrimp in it, but it has a lot of them and I feed them a lot, I've never needed to clean it out since I set it up in October (I've only ever opened it to add carbon in emergencies).
I run a 305 on a 190L planted tank too and also find it excellent.
I have one of the 200 l/h Eden clones (Resun CY-20) running on a 15L and it's OK on that, it was also good on the 25L planted tank I had in the past, but wasn't nearly enough for the ~60L tank though, I had to supplement it with a fluval 3 internal.
They are quite a pain when you have to clean them out regularly, I wouldn't recommend them for anything over 25L, and even then only if it's lightly stocked. Only cost around £15, got to say they are good value.
