oh that it does, but really I look for gph rather than anything else. look at the ratings for any 4 filters.... lets say....
for 93 gallon tank
30-80 gallon tank
100 gallon tank
tetra EX 20
20 gallon tank
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!
