Eheim Classic 2250?'s

[Scottfree]

Howdy,

I always like to have as little clutter in the tank as possible. 2250: One intake, one outlet. Two 2217: Twice the tubing, two different spray bars etc. IMO the great advantage of one big filter over two small ones is the sleeker look of the tank. The money spent soon becomes irrelevant when you think about what you're gonna spend on fish

Good point, I'm with you on the sleeker appearance, there are pluses and minuses to going with One filter versus 2, I would say in the long run, I'll only be using 28 watts, instead of 40, that could be the potential payoff in the long term....

I bought my first canister filter a few weeks ago - an Eheim 2217.

Awesome filters! The simplicity of the design is impressive, and I'm really happy with it. The flow was a little too intense for my goldfish, but they are getting used to it

Ok, just a request from anyone that has a classic eheim setup. Could someone take a couple/few pictures of the setup and post them on here? I want to see how you have the tubing setup with quick disconnects..... Thx in advance

Well the Back wash you don't have in the 2250 harleyK the 2260 comes with a little piece of a tap on the bottom of the tank to let you back wash. the 2250 doesn't come with that tap on the bottom of the filter. i have used the 2250 and now i'm running the 2260 because it's a little bit more filteration and the double tap connectors for it is a good thing to have when it comes to cleaning the filter. if you don't mind pulling the drain pipe out of the water line then without the taps are okay.. in my filter i have the bottom as eheimech then a bag full of eheisubstrat so you don't have to dig them out while cleaning the filter. when cleaning filter i just use the clean aquarium water into a tub and then dip and rinse it out while the eheimech i just a hose to wash it out. then i have filter floss on the top to filter out what the eheimech didn't do at the begining of the filter journey.. just want to know what size tank are you using this 2250 on??
good luck and still a good filter to begin with.. little bit exp of course w/out media and taps.

One of the problems with having the media bagged is that the bags themselves act as a mechanical filter and unless you leave a LOT of bypass room they tend to clog the cannister really quickly.

Backflushing is the best way to clean these filters out. Having an extra quick disconnect attached to a piece of hose is the simplest way.

With ANY cannister...keep the hose runs from the tank to the cannister as short and streight as possible to reduce head pressure while leaving yourself enough extra for servaceing. It's also a good idea to mark the hoses with colored tape or shrink wrap to keep from mixing them up. Sounds silly I know but anyone whos used cannisters for a LONG time knows how easy it can be to reverse them when your in a hurry.

I have only reversed the hose a couple times... couple hundred. Marking which one is which is even better, as I still mess them up with colored tape.

I used to use quick disconnects that where differant on each end and then reverse them on the hoses...Male/female....female/male. That made it impossible to screw up. It's no longer an issue with the 404/405s but I had to go back to the tape for the FX5's lol

I guess I may not understand your point. How would the bags clog the canister any faster than it should be clogged. If the waste load is there, wouldn't you want it to be captured?

I can clear that up for you... The problem is not the bag trapping debris but the fact that it does it in a very small space. a single line in the cannister if you see what I'm talking about. This forms a barrier quickly. Sponge media and the like dont trap the debris all at the same level so they can collect a lot more of it before the filter starts to slow down.
