Eheim Canister Filter Comparison

[Cyberkinetic]

I took out the diy prefilter foam as well as the inlet piece to clean earlier and while the prefilter seemed ok, not that badly choked, it's the inlet preece with the slits that gave me a shock! There's a piece of gunk, the height of almost an inch that was inside and it reduces the water flow to less than 25%.. So I quickly took care of that and gave the prefilter a good wash before fixing it back into the tank.
But it didn't solve the issue, still the rattling noise and it's really loud now. No choice, I decided to clean the internal of the filter and replace the fine filter wool. It wasn't that bad really, light brown but not choked with gunk like what I've seen on my hob filter wool previously, but anyway, changed it to a new piece. Did a quick rinse of the two trays by just jiggling it in a tub of tank water, it wasn't too bad either. I decided to reuse the coarse filter foam after giving it a good rinse.it's surprisingly clean as well.
Fitted everything back quickly and powered up the filter. The loud rattling sound was gone, but still if you go very close to the filter, you will be able to hear a slight, soft noise from the filter. I tried tilting the filter about but ths sound still stays.. Not sure what else I can do.
Oh, I did take out the impeller to clean as well. Also checked the tubings and there's no obstruction (it's just one month old).
anyone can help? Thanks...

Thanks bro xconnect, will try to clean that up tomorrow..

Hi fellows, I have a question: how does a chiller, which has. I suppose, rigid inlet/outlet diameter, get connected to canister filters of various hose diameters? Does it mean for filters using certain hose diameter, I may have to get step-up/step-down adapters in order to connect it to my chiller?

[Navanod]

The inlet/outlet hose barbs are not rigid and can be unscrewed and changed. Most chillers come with 2 or 3 inlet/outlet sizes that can be fitted onto the chiller. Common sizes would fit 12/16, 16/22 and 19/27. 19/27 is more common for larger chillers and Arctica.
Step up and step downs cannot be avoided at times. I even used my chiller as a step down before (by using 19/27 as inlet and 16/22 as outlet, so I can fit it to Eheim installation kit), although it really hurt the flow rates.

It is only a problem when buying 2nd hand chillers, because most people would've lost their other inlets/outlets except the ones currently in use. I only had to buy a pair to replace the ones on a Resun. Costed me about $25.

The price of eheim is out of my reach...

You can always go to the buy sell market place and buy 2nd hand eheim filter. As eheim filter can last very long

[Cyberkinetic]

Phew... My 2224 just went back to "silent" mode finally...

Don't understand why also..before I did my routine water change tonight, the sound although very faint is still there. Then after I switched it off to do my water change, and power it up again, the sound is gone.

Tried.on/off a couple more times and it was good still.. *shrug*

i using the pro II 2026... solved my leaking when changed o-rings....i find it quite good but recently find my water flow output getting weaker and weaker... what is the cause? please help?

last time C328 uncle say my hose angle maybe stuck with air bubbles..so went to cut the angle of the input hose...solve for a while but problem seems to come back again.

will test it with a pail of water with the head to see if the shooting power is still that great tommorrow.

others with the same problem as me please do kindly advise thanks. forget to say it connect to hailei 300A chiller.

when the last time you clean your filter?

[ralliart12]

Hi fellows; I have some questions with regards to the instructions for the 2073 model:



Qn1. What is this "Easy Clean" function about? Is it like the "back-wash" function of the classic series?



Qn2: What does the "bleeding" refers to?

Qn3: How come the manual warns not to fill the filter canister before priming? I have the impression that a fully-filled canister is more easy to prime? Or is there some reason not to fill until the pre-filter tray (meaning the bottom 3 trays can still be filled with water & media) if you are using the suction aid to prime?

[Navanod]

Q1: I referenced this page
http://www.eheim.com/en_GB/products/...s/professionel
It says:
Individually removable filter baskets for filling to suit individual requirements; models 250/350/600 with cleaning grill ‘Easy Clean’

Basically, the bottom of the trays is a grill that makes cleaning easy because it can be flushed out by running water over the media. Nothing really new actually. Not the same as backflushing on the Classic. I did try to backflush the Pro3e canister before by running the water in reverse passively through gravity and it does seemed to work as I get some dirt coming out and the cleaning indicator went back up.

Q2: "Bleeding" refers to ridding the canister and the hose lines of any small pockets of air.

Q3: "Priming" refers to filling the canister with water BEFORE powering up the pump/impeller. Impellers cannot move air or exert suction, so an un-primed canister will not "suck" water down from the tank. It'll also burn out the impeller. So by priming, we try to fill the entire canister with water all the way from the inlet pipe to at least part of the outlet pipe.
A fully filled canister is therefore already primed and erm, not easier to prime.
In the older models and other cheapo canisters, priming is done manually, by sticking the inlet pipe into the tank, and sucking on the outlet pipe by mouth. Like sucking on a giant straw, water will move into the inlet and once past a certain point, gravity takes over and the canister will fill.

In Pro 2 and Pro 3, there is a "priming button" or as the instruction calls it, the "suction aid". This creates the initial suction to draw water into the inlet so we do not have to mess around with the outlet pipe and drink tank water by accident.
It's not just the prefilter that must not be filled for this to work, the entire canister should be empty. When water gets sucked down the inlet pipe, the air needs a place to escape in order to bleed the canister. The only way out for the air is via the outlet pipe. Having any water at all in the canister will create an airlock that blocks the exit path of the air and prevent more water from entering the canister.
It is possible for the suction aid (by pressing it like mad) and the canister impeller itself to bleed small amount of air but not large pockets. The canister will simply just stall.
If you wish to fill up the canister before hand, it must be totally filled up with water, including the entire inlet pipe from tank to canister. In practice, it is actually very difficult to do, unless you use the installation kit, which has a cap at the elbow that can be removed for filling. Even then, I find that I'll still somehow have air pockets in the canister that will then merge and choke at the outlet pipe.
Give it a try yourself and you'll see what I mean. Its quite difficult to explain fully in words.

This thread soon will change into the ehiem helpdesk soon.

Guys, keep thread from going out of topic. It will be easier for people when they actually search for topics and try self help.

Thanks.

@felix, understood, i.e. you have a valid point.

[aquarius]

Maybe someone should start a new thread called Ehiem Helpdesk? So that all the Ehiem related queries/questions can be consolidated into one thread for easy reference and reading.

I think 2026 & 2028 works well for me~ serving me for many years and motor still running strong~

[alikao]

I have been using my 2217 on a 40 breeder for 2 years and a 2215 for over a year. I can't say enough about these Eheim classics. They are a work horse that keeps running. Quality of the canister is very impressive. Importantly, the classic is super quiet.

I am thinking of getting Eheim Ecco Pro 300 for my new 36 by 18 by 18 tank...How is the power consumption like? Is it overpowered or underpowered?

I used the Classic 2213 filter before for my previous 2 feet tank and it is really good and reliable. I may get the Classic 350 2215 model if I get bad reviews about the Eheim Ecco Pro 300.

Just re-posting my reply from another thread... more relevant here for reference.

I'm using the Eheim Ecco Pro 300 for my 2ft planted tank and i find that it's just right for that tank volume of around 64 liters. It runs at 750 l/ph flow rate but uses only 8 watts, therefore quite energy efficient.

For your planted 3ft tank and intended bio-load, that filter model would probably be too small for it... you should look at larger filters with higher flow rates instead, try to go for 8-10x tank volume turnover as a guideline. A higher flow rate is needed in planted tanks to create sufficient circulation to get nutrients and Co2 to all the plants, especially when plant growth becomes dense.

So for a 90cm x 45cm x 45cm tank, which is around 180+ liters, you should be looking at much larger filters that run at 1,800+ l/ph (or maybe install 2 filters that run at 900-1,000+ l/ph each, could help cover dead spots more efficiently in the tank too).

Ok thanks. I had been out for 5 years and my previous tank was a 2 feet by 1 feet tank. Was thinking for going for 3 feet by 1 feet tank.So which Eheim external filter do u recommend? Going to order the tank when I move into my new BTO in 3 months. Will stick to Eheim filters though...

If you have the budget... maybe go for an Eheim Pro 3e 450, has 1,700 l/ph and all the fancy electronic monitoring systems.

Otherwise, maybe can consider 2 x Eheim Classic 2217 (2 x 1,000 l/ph) or perhaps 2 x Eheim Classic 2215 (2 x 620 l/ph), those would be simple and easy to use.

Btw, if you are going for a 3ft by 1ft tank, then that would be much lower volume then a "standard" 3ft x 1.5ft x 1.5ft tank, so you can go with less flow rate to match the smaller tank volume. Maybe just one Eheim Classic 2217 might be sufficient already.

[RenesisTurbo]

I have decided on a 36 by 18 by 18 tank.....Think will get the Eheim Pro 3 350 external filter.BTW, what is the capacity of a fish tank that is 36 by 18 by 18?
