Eheim Canister Filter Comparison

[Navanod]

My own idea is that it's a space for any creatures unfortunate enough to get sucked into the canister.
I always find shrimps (adult ones!) in that space in my canisters. They were sucked in as shrimplets and grew up there.
I've tried placing some CR very sparsely there and it didn't affect flow. It's meant more for future shrimplets to hide in than as filter though. Haha

good idea. haha. but i dont think i am that hardworking to always check the canisters. mine has been running for 4-6 months and never maintain before. haha

Yesterday (while doing maintenance on one of my 2224s) I tried moving the 2 pieces of default cotton wool to that bottom empty space & have the 2 media trays filled solely with Biohome+, & added a single piece of MagicClean fine filter cloth to the top of the "last" media tray. Flow rate doesn't seem to diminish much, if at all...

Its still too early to tell bro. Give it a week or 2

Hi Guys

All of you know that Eheim got many model of canister.
Which is better or which do you prefer most? Why?

Definitely Eheim 2213, classical, easy to operate and makes water crystal clear in my 2 ft tank!

[G&A Associates]

Hi all,
May I know, will 02 sets of 2213 sufficient for *3FT by 1.5FT by 1.5FT?

[Antonchann]

Actually I'm curious if there's any detrimental/dangerous issue to fill up that empty space, as I've come across a few sites that said the empty space if there to "collect" any relatively large particles & prevent them large particles from reaching the media stages/trays at all. But if that's the only reason for the empty space, wouldn't some coarse mechanical media there be even better?

I use Eheim Lav for that empty space. Very Good..does not affect flowrate at all.
Very cheap too.. $11 for a litre. I think its one of those under-rated mechanical media out there.

Hi fellows, may I know if it is possible to claim warranty for an Eheim canister filter if it starts leaking simply from me filling up the canister fully with water (& not even powered on)? I observed no visible cracks on the canister body.

[xconnect.]

maybe you overfill it.or maybe your oring spoiled.can i ask what is your canister model?

[felix_fx2]

Still covered?
Leak from body must have crack. Shine torch light ?

[ralliart12]

maybe you overfill it...

With media? But I ran this "stress test" with an empty canister & just tried to get the motor running.

The reason I'm running this test is because the canister leaked during operation last weekend. Hence, I am testing it.

...maybe your oring spoiled...

Which O-ring (s)?

...can i ask what is your canister model?

2224.

Still covered?...

Do you mean if the top cover (thick gray section) is still on? Actually, I do not get what you mean?

Leak from body must have crack. Shine torch light ?

I strongly do not think there is any crack in the body (the translucent green portion), but I'll do another test later, i.e. just fill up the green canister with water & observe if any traces of water drips out.

[ralliart12]

1 additional question fellows:

Are there opaque (black preferably) versions of Eheim hoses? I'm getting sick of algae/crud/whatever nonsense growing on the inner wall of my normal translucent green hoses.

[ralliart12]

...Leak from body must have crack. Shine torch light ?

I ran another leak test:



As observed from the video:
I fill the empty (no media, no tray no nothing) canister partially with water, replaced the top grey cover & start topping up the remaining space with water via the inlet & outlet holes of the top cover. Almost immediately (1min11sec-mark & 1min33sec-mark of the video) , water started leaking from the spots where the 4 hinges are (clamping the cover shut). I don't think this is supposed to happen. Besides, that how I usually top-up the filter with as much water as possible to make priming easier. I can't imagine what will happen with the canister actually powered on & running, & filled with media & such.

Erm, so, now what fellows? Claim my warranty or buy spare parts? What's damaged any way?

I SEE UR MISTAKE ALREADY u pour the water TO THE HOLES ONLY U LIKE this sure leak because inside the ehiem designers good they dont want you breed mossies when there the space near the hole so that is actually a safety feature NOT ur canister leaking. you try redo but you do dripping method to the hole and fill make sure no water escape to the empty space.BECAUSE i ALSO OWN A 2224 and i found out. i almost want to knock my head to the wall

[ralliart12]

...TO THE HOLES ONLY U LIKE...

Can you elaborate on this? I really do not understand.

Sorry, just saw your message this morning. I fell asleep last night after my previous post.

Oh I finally get what you mean. Let me rephrase what you said:

I see your mistake already: you should pour the water through the holes only. If you do it like this, i.e. just blatantly pouring the water into the general cavity around where the 2 holes are, surely it will leak because inside the top grey compartment, the Ehiem designers are good in that they do not want you to breed mosquitoes where water can accumulate in the space near the 2 holes. So that actually is a safety feature; NOT your canister leaking. You can try re-doing the test again, but this time round, fill the canister strictly via the holes only...

Is that what you were trying to say?

[xconnect.]

Yeah I use dripping method when the filter is going to be filled so I can minimize leakage.

[felix_fx2]

I need a hammer.

You prime wrong way/pour too fast.
The inlet outlet which was removed, has a o ring there. (xconnect, confirm that for me please. Thanks )

Most canisters below the cover of that top section which house the powerhead/impeller section has some space. IMHO you were like pouring it right down.
