advice needed from expert on Eheim pro II water flow.

[granzord]

recently my output from eheim pro II is getting weaker and weaker...like tap water flow from your hse tap.... any expert views. is it my turbine is spoilt?

1)I take ouut my eheim pro II head ,put in pail of water. the water shoting out from the output head is good.
2)I take out the aircon input as my canister is connected to chiller...i on the set and test the output, damn lousy flow...
3) I flush the chiller , connect to canister. output at my aqauirum tank is still not good.

any advices?

is the turbine at my head is spoilt, how the damages? any one got my experiences.

Thanks,

Lastly like to check if eheim 2217 same power rater as eheim pro II ? chiller is 300A hailea

Bro your eheim is 2026 or 2028 anyway for 2026 is 950 liters per hour 2217 is 1000 liters and 2028 is 1050. Nvr see you lately at tiong market XD anyway your filter have you tried to open the whole filter to see you can check the rotary thing Inside and see if Is broken, and maybe your o rings on your filter is old already and may be causing the water in your canister to mix and this will cause decreased flow rate. And maybe our pipes are bent so will decrease flow rate. Or maybe your chiller got somthing wrong ?

If I read your post correctly you were asking if there is something you can do to increase the flow rate of your eheim.

The following few factors will affect the flow rate of your eheim:

Cleanliness of the impeller:
This is essentially the "pump". On the "cover" of your eheim, you will see a compartment where the impeller sits. That impeller can be removed, together with the ceramic shaft, for cleaning. You will notice that the vanes of the impeller is covered with slime. Use a toothbrush to give it a good clean. Also clean the housing of the impeller using toothbrush or something similar. Be very careful not to break that shaft when you assemble back the impeller.

The media of the filter
Very often I notice hobbyists pack alot of media into the trays. Filter wool especially, will significantly slow down the flow rate if it is packed too tight.

Hose configuration and the length and the cleanliness
Your eheim will lose power if:
- The hose is unnecessary long
- There are "bends" along the hose, or there are very abrupt bend along the hose
- the water is made to go through too many device such as CO2 reactor and chiller.
- your hose is dirty.

Your tank height
The "strength" of the pump is defined by "head" which is measured in meters. The higher the tank the more power is lost to overcome the height.

Yoz bro, last time the flow is very strong... recently my flow is getting weaker and weaker..everything is still the same...the length of hose .... listen to advices , think is the impeller problem, but how to check ???

[Nicky]

If your eheim is a 2026 or 2028, you should be able to see something spinning below a "cover" underneath the filter head unit.
That "cover" has a level and you need to give that side level and push and a pull using your finger, and that cover can be removed.

Once removed, you can just use a little force to pull the whole impeller out. What you are tugging-at to pull the impeller out is the one end of the ceramic shaft, which is covered at the end with a rubber stopper.
You should have a rubber stopper on each end of the ceramic shaft.

To check the impeller, take out the filter top and and disconnect the hoses and put in into a pail of water. Then turn the power on. If water shoots out strongly the impeller is ok. If water does not shoot out strongly it can be the impeller or the motor. Impeller is costly about $40. Not sure how much motor costs? Anybody who knows how much motor costs can post for our info please. Thanks.

I thought the impeller is mainly a magnet with fins? Why does anyone need to change the impeller?
To change the motor one might as well buy a new filter.

Agree with bro Nicky motor change most likely buy new one already .impeller spoil maybe because running filter without water, impeller was dislocated from original position due to transport of filter

Hi bro , i tested with the above method. i put motor in pail , water shoot up strongly..... as my canister ( 2026) is hooked up to hailei 300a. I took out the input to chiller and on the canister...water flow is very minimised....flow is weaken...therfore checking with your guys any experience on this issue?

[xconnect.]

Hey I think you bring your ehiem to my place I help you inspect if ok means your chiller may have something in it

[granzord]

lol thanks everyone for the tips. i think buy new one better haha. actually last time , i face leaking problem so i change all the O-ring. leaking solved.

recently surface this problem. during the day, my dad heard a loud explosion. he though light bulb burst. not really sure it is link? told my friend about this , he suggest maybe my impeller is spoilt as usual to this model , everytime leaking and impeller problem... he also suggest i flush the chiller.

therfore i do all the steps at a go. all the hose is same as last time when the flow is strong and heallthy.

1) test motor head in pail of water - result : water shoot up strongly.
2) canister output to input of chiller> took out input chiller > on canister> flow is very weak....
3) flush my chiller > put back as usual > on canister > flow is weak.

later my friend told me maybe impeller spoilt?
any advice, any bro here experiences this issue before with this model ( eheim pro II 2026) ?

Thanks once again for the great help offered.

lol thanks bro , think your place nearer to mine haha . will pay you a visit soon . when you free . i think i bring my canister head to your place for a checkup and x-ray.
actually this model is good except this few pesky problem.... maybe i will downgrade to eheim 2217 if dead cert issued by bro xconnect haha. simple still the best for me.

1st warning on SMS lingo guys...yes, granzord and xconnect, you guys.

It is unlikely that the impeller or motor is damaged. If either of these are damaged, the thing would not work at all.
Running without water will burn the motor, but moving the unit should not dislocate the impeller as the 2 rubber caps will secure the shaft of the impeller.

First, check that your media trays and sponge inside are not choked.
Next, make sure all the O-rings, especially the ones on each of the media trays, are still good. If they are dry, cracked and does not sit well, you'll lose flow from backflows.
Flush your chiller chamber, if possible, reverse flush. It's unlikely, but dirt may add to the resistance of water through the chiller.

Note that adding a chiller to the loop can add about 1.2-1.8m of head resistance to the pump/canister so a 2028, with a head pressure of 2m, would be quite crippled by a restrictive chiller. If the canister have to fight 1.5m of resistance, it'll only be left with 1/4 of its max flowrate, or ~260L/H.

Head is also affected by amount & type of media in the canister, how choked the canister is, length of pipe and height it has to pump up to the tank (although this is less of an issue for canisters, since its a closed loop and the returning water gets help from gravity).

Pro two personally it has to many parts hence higher chance for damages and that =wallet flat
My pro only quick release valve's o ring which cost me 3$ nothing else spoil( touches wood )= wallet abit damaged
Classic lagi(even best) only motor hence most cost saving among the ehiem series only I know The clip at the sides need handle with care if not break BUT still can use.=wallet full full

[xconnect.]

Sorry for lingos. And also I forget about the orings also will affect but Bro grantors say his Realative heard a loud bang so must be somthing spoil or damaged

[granzord]

finally the flow is good. i found my hose for the input to the canister got trap air inside, water being stuck halfway ... then i release the hose to a pail, the water begin flowing like hell... into the pail. then i connect back to my canisterer. bang . the flow back to normal but not as good as before but still can create whirwind.... i hope problem solved , will monitor for a week to decided.

Thanks to all bro here for advice. is being hell of a week for me.
