Hi Beverly,

But he is using it in FW. You WANT it to be a nitrate factory! Not that I am saying cleaning 3 or 4 times is good or bad, it just depends on what he is using it for.

Hi bulletsworld,

Yes, eheim is a lot more expensive. But for me, it does cost cheaper to get a eheim right away than to buy a 403, 404 and end up buying a eheim anyway.

Here is my objective (atleast try to be) comparison between Fluval and Eheim Professional 2026.

Flow rate:
The initially flow of Fluval is greater but it does slows down significantly especially if you are using it on planted tank. The Eheim is able to maintain the flow a whole lot better.

Filter Media:
I think both contain roughly the same volume. However, fluval does offer more compartments and places for sponge. My eheim only have two compartments.

Cleaning.
Although 404 has a big improvement in ease of cleaning over 403, it still doesn't even come close to the eheim. If not close properly, my fluval will sometimes leak.

Priming.
My fluval takes a long time to prime after each cleaning. I sometimes need to shake the filter to get the air out, etc. I does take a while for the fluval to get going again, most of the time, there are lots of bubbles. I never have this problem with my eheim as long as my water level is full.

Quality.
My old Eheim 2222 just seem to out lask the two fluval. I got two friends who also own 2 fluval 404. Between us three, we have problems with sealing, motor, the plastic locking thing, etc. The eheim is a much better build.

The two filters does look similar and do the same thing but so does BMW and Ford.

I think the best way is to go to the store and play around with the filter to try it yourself.
