it seems to be like the problem was not necessarily the filter but the size of it.

the eheim classic 2215 has a flow rate of 163gph, and the 405 has a flow rate of 340gph. dont blame eheim because you didnt read the specifications.

Yeah, except the Eheim 2215 says it handles up to 93-gallon tanks. I have a 55 and it started crapping out within a month. If you want to defend Eheim for that, than go ahead.

Go Fluval! Thank you for the EASY design and function. And the DVD!!!

It's all luck, I guess. I have had no problems whatsoever with any of the 4 Eheims I'm running. I cracked open my 2217 for a cleaning today after 6 months and found I could have let it run another 3 to 6. I don't have a bad word to say about Fluvals except that I was once warned away from them - and I no longer recall why. I have the same sort of problem you had with the eheims with a Magnum 350, but I have a friend who swears by those and never uses anything else. Go figure.

Logic is only the beginning of wisdom

oh that it does, but really I look for gph rather than anything else. look at the ratings for any 4 filters.... lets say....

eheim 2215
for 93 gallon tank
163 gph

emperor 400
30-80 gallon tank
400 gph

100 gallon tank
350 gph

tetra EX 20
20 gallon tank
110 gph

for the 2215 thats 1.75gph per gallon
for the emperor thats 13.33gph per gallon
for the magnum thats 3.5gph per gallon
and the tetra thats 5.5gph per gallon

its kinda like that commercial, you can make 100% of all statistics say whatever you want 50% of the time. each different company has completely different standards by which it determines the recommended tank size, and as such the numbers are almost completely useless. the only thing worth while REALLY is the media capacity and gph, because those cant be spun, for the most part.

if youre happy with your fluval than im happy, they make a great filter! My only recommendation is the next time you go to buy a filter dont read too much into the box. the person who wrote the crap that goes on the side of it doesnt necessarily take into consideration the bioloads of different fish, each persons individual tap water quality, stocking, so on and so forth. the GPH is where its at :)

congrats on your fluval 405!
