i would disagree, and say go with the 2215. its not that much more expensive (idk where your from or how much 1.1k is, but last time i checked the prices were pretty close)

I had a 2113 on a 10 gallon and it was perfect, i couldnt imagine it being good enough for a 17 gallon though..Yes others have had different experiences than me, but thats what this forum is for - to get diverse opinions then make your own decision.

the 2213 MIGHT be enough flow for your tank, but the 2215 WILL be enough. The extra room for media in the 2215 only helps your tank! You can always turn down the flow of the 2215, you cant turn up the flow on the 2213. Yes you COULD add a nano koralia powerhead, but that would be more expensive than just buying the 2215 upfront, plus that would be another piece of equipment in your tank and another thing that needs to be plugged into your electric.

If you go with the 2213, i would bet that within a year you wish you just shelled out the extra cash for the 2215.

All depends on your scaping and setup for the tank.

then again, i totally agree with this..

hmmm... you do have a point... actually i heard that, 2213 has an issue with the flow rate...anyway I am from India. the local dealer said that, I will definitely have the problem, so go for 2215...but after seeing the eheim site, and their specs list I got confused...because according to them, even 2211 is enough for my tank size...so I thought why to go for 2215...So asked the question here in the forum with the hope to get a proper solution...thanks for the suggestion man...Any idea with ADA Bio Rio? will it create clogging???

yepp, no problem. im sure the 2213 would be adequate for biological filtration, but for the sake of moving water in the tank i would go for the 2215. (then again, i havent seen either filter on a tank of your dimensions!) No clue about the ADA filter media, i only used what came with my eheims

Why, what's going to happen within a year?

lol, got me there. nothing. im just saying- i bet he will look back and say "i wish i bought one size bigger" a year just seemed like a good enough time frame

i think both filters will work out for you. they are essentially the same thing, one is just a little stronger (plus a little more room inside the filter for media, but lets forget about that)
the 2213 would work, but i think you would be happier with the 2215.


it would be nice if a few more people chimed in to voice their opinion
