Eheim 2217 (Filtering a 125)
- Thread starter Big_Kill
- Start date
I have a 2217 on one of my 75's and an AC110 and a power head with a sponge on the intake of it. The 2217 alone wouldn't cut it on my 75 let alone a 125
i'm a big fan of the eheim classic cannister filters...very quiet and reliable, use relatively little energy, but they all have low flow rates compared to the competition...so another filter would be ideal...even an HOB to mix it up
i believe the slow flow rate helps break down ammonia, etc. eheim is are by far one of the best biological filters. you can add a power head facing down to kick up most of the poop to be sucked into the filter.

One would think that if they were lying...that they'd say you need more product or a bigger model so they'd make more money. While I don't think that a 2217 is enough for a moderately stocked 125, I doubt they're lying about anything.
I have one 125 already. I filter it with two emp 400s and one eheim 2213. In my fish room I have a linear piston air pump and I filter everything with sponges. My other tanks that aren't in the fish room have to be filtered seperately. I only keep cichlids (central american) so most of my tanks are lightly stocked because they don't get along with each other 
I also do large weekly water changes sometimes twice a week. You can call me crazy but I actually believe the manufacturers claim that a 2217 can keep up with the bio-load of a lightly stocked 125. However, I am concerned about having dead spots, stagnant water, etc. Im hoping to get an in-line heater for this tank because I don't want much of anything inside the tank. I don't want power heads, hob filters, heaters, etc. I might have to go with the 2250 or 2260 and see what happens.

x2 . . . Eheim puts more emphasis on exposure-time, not flow rate
I like Eheims, but I do agree that they are not the best when it comes to pure water-polishing . . . I use them primarily because they are dead-quiet, easy to use and extremely reliable . . .

84 people who actually own the filter have told you it's not enough. The rated tank sizes are good for comparing models from the same manufacturer, but that's all. That number is just calculated based on the flowrate of the pump, volume of the canister, diameter of the tubing, etc. It doesn't mean it's actually a practical, useable number. If you poured the contents of your tank into a giant funnel and into the intake of a 2217, it would probably remove all ammonia and nitrite as this filter is excellent at bio-filtration. But it simply doesn't have enough flow to reach all areas of a 4 foot tank, forget about a 6 footer.
