I just received my new(this filter) filter and I have some questions. The instructions do not give a lot of info ( in English)
I purchased the Ehiem ecco 2234 over the classic because the seller advertised an adjustable flow rate….. There is nothing in the directions about adjustable flow rate.

Can I adjust the flow with the shut off valves?
Is there any harm in running a filter rated for 60 gal in a 29 gal tank?

I am currently terrible under filtered with a whisper 20 HOB. The only media in the filter is white floss.

Can I simply place the old floss in the new filter until the new media is seeded or should I run both filters for a wile simultaneously?

The new filter comes with a white and blue sponge pre-installed in one chamber, 2 empty chambers and 2 bags of small “bio balls” clay I assume.(and a carbon pad I wont use but will save)
Do I need to fill all three chambers?
Should I use both bags of bio-balls or split one bag between the two chambers and save some of the media?
If the aggregate media are bio balls do I save that stuff indefinitely and do I replace the sponge/floss periodically?

I wonder if I should have ordered the classic instead of the ecco.

Thanks,

Tony.
 
I have the eheim classic series but I will try to answer some of your questions. As far as taking the old media from the old filter and putting in the new filter to seed it, I think that you can do that. Just slip it into one of the empty chambers. In a few weeks you can remove it after the new filter is seeded. It is not necessary to use all of the chambers if you do not want to. You can place extra media such as carbon if you so desire.The bio-balls I would put all of them in the chamber unless the instructions say not to. The more bio-media you have to colonize the good bacteria that your tank needs to thrive, the better off your tank will be in the long run. The directions will tell you that you have to replace the media every now and then but it is really not necessary. If you do that you will throw away a lot of good bacteria that your tank needs. I would just rinse it in some tank water when you open the canisters for maintenance and then put it back in the canister. They will not have to be replaced unlesss they are so old that they are disinergerating. If you do feel the need to replace some of the media, only do some at a time and some later. That way you will not throw your tank out of balance into another cycle.

I have eheim canister filters going on two of my aquariums, and I have to tell you I love them. They are fantastic filters and very quiet. Thiere performance cannot be beat and is outstanding. I'm sure that you will be very happy with it.

Hope this helps.

Good… I’d really like to get rid of the noisy little “whisper 20”. It is unreliable, quickly overflows, and makes CO2 regulation uncertain. I will keep an eye on thing in case there is a mini-cycle. I did decipher the filter order. It’s not in the written instructions; it’s pictured on the box. Course sponge- bio-media (substrate)—fine filter pad

Does anyone know how the so call flow regulation is supposed to work? Can I use the gate valves at the connections or would this strain the pump.
Also, can too much filtration become a problem? (this pump will graduate to a larger tank when I move & 29 will become hosp’/ quarantine)
 
Perhaps this thread should have been posted in the Newby forum. Certainly wouldn’t hurt my feelins’ if it was moved… :dive:
 
I don't have an eheim cannister filter, but my experience with cannister filters is that they are less strained when allowed to run fully opened. Unless its just too much current for your aquarium you should probably do just that. Many of us on this board run more filtration than what is needed. I myself have a fluval 104 rated at 100g capacity on a 50g aquarium and it does a great job for me.
 
What a great piece of equipment. The primer is easy and allows you to pump all air out b4 starting the filter. It is quieter than the lighting ballasts. The CO2 bubbles hitting the bend of the intake is now the loudest noise the tank makes. Most of was commonsense once I started puttin’ it together.
Thanks y’all... Think I just needed Mom (marinemom) to hold my hand. Now that it’s runnin’ I see no reason to reduce the flow.
