Canister Filter?

This is a discussion on Canister Filter? within the Beginner Freshwater Aquarium forums, part of the Freshwater Fish and Aquariums category; --> I was thinking about the Eheim Professionel 3E model 2076. Would this work good on my current 27gal than possibly on a 60 gal ...

P.S. man the additional filter set is expensive

Wow, this is a "cadillac" of filters. No wonder it is so expensive.

This is too much for a 27g, and even for a 60g in my opinion. It is rated for up to 110g. I always select a filter with a top end rating (110g in this case) close to my tank. I would use this for instance on my 115g, maybe my 90g.

But it has features I wouldn't want. Wave action for one, that would be very stressful to me, and I suspect the fish. This is not natural to forest fish. And I don't understand the day/night bit; I could understand temperature variances between day and night, but not water movement.

I would look for something more basic.

I see, can anyone recommend an Eheim canister filter that would work on my current 27gal and later on a 60gal tank? The main thing I'm looking is for it to be really quiet, easy to clean, and easy to setup (like priming). I'm open to any suggestions since I know very little about this subject.

If you really only want to buy one filter, then it should be one rated for the larger tank. The issue then is that it will be too much for the smaller. But adjusting the flow to minimal might get you through this. You mentioned goldfish previously, for the 60g I assume, so you want a filter capable of handling messy fish, and also plants will likely not be present or very tough ones which are slower at assimilating nutrients (goldfish eat tender plants).

If you want Eheim, go to their site or a site like Big Al's or Drs. Foster and Smith and review the filters. The tank size recommendations are all included.

I'm in the long process of shopping for a canister for a 55G. I've been milling between the Rena XP2 and the Eheim Classic 2213. I read the reviews. They both seem good, I'm right along with the OP for some feedback of owners if they are pleased.


I'm also looking at the 2215 as I'm thinking of a 75G in the future.

Don't forget to answer TwinDads question, don't want to bump him.

So does the rule of 8-10 cycles of tank water per hour still stand for canisters? I guess that's where my confusion is coming in. I currently have the Marineland Pengiun Biowheel 350, that moves 350gph.....should I not being trying to match this flow rate with a canister?

Bryon and a few have mentioned that while it's good to cycle as much water as possible you have to consider the plants and inhabitants of the aquarium. Bettas for example don't like much water movement so what good is a 1000GPH filter when it's not natural to them. So you do have to consider the plants and fish in your filtering. On the same note if they like a strong current that would need to be provided too.

I was originally going to go with the highest GPH model, then I stared to read around and second guess myself. So now I've come down to getting one rated for the 75G. Just curious on experience.

I don't mean to threadjack here, just thinking that it would be relevant information for both of us almost same aquarium situation here.

Filtration should always be based upon the fish in the aquarium. Not all fish need the same type/extent of filtration [thinking here of filter equipment, not "filtration" in the sense of water quality which obviously always needs to be the best we can provide].

The OP mentioned goldfish; a filter for goldfish is a very different matter from a filter for the same sized tank containing plants and forest fish. And it would be something different again for a tank of fish from rivers with strong currents. When planning an aquarium, the first consideration should always be, what fish will be in it. Tank size and type (long vs high), filter, sometimes light should be geared to the fish community.

I do not believe that faster water flow through the filter (this being the gallons per hour issue) is better filtration. It often is not, and there is plenty of scientific fact to support this. All aspects have to be considered. The fish load will impact the organics, the filter has to be able to handle these, but at the same time pushing the water through 20 times instead of 10 times each hour, for example, is not necessarily going to mean "better" water quality. There are too many variables.

So if the idea is to make the filter media the best to filter the water. Would it make sense to get a filter that has more baskets? I've read the use the pre filter plastic balls, then sponge, then bioballs, then fine filter. That would be very well filtering the water, but would seem to need a higher end pump with more capacity, which comes with GPH.

This is what I was getting at previously. What possible good will more baskets do? [Not being facetious, please understand, just asking the general question.] The answer is, nothing.

The nitrification bacteria that colonize surfaces can only exist at the level required to handle the available ammonia/nitrite. No more, no less. And there are more of them in the substrate than in the filter. So providing double the media achieves nothing. However, it can backfire, because the heterotrophic bacteria will colonize everything, and smother the nitrifying bacteria.

Now, pushing the water through filter pads/floss/sponges is quite different; here we are filtering out minute particulate matter. But unless the tank water is cloudy with garbage, this is not necessary either.

Pushing the water through faster can also be detrimental. The bacteria can only handle the ammonia/nitrite as it comes to them, ad this works best with a moderate flow. Much the same as plant nutrients; in fast flowing water, plants assimilate far less CO2 and other nutrients because they flow past them too quickly.

It comes back to my original point. The fish have to be balanced for the water volume in the tank, not more. If this is done, then the filter rated for the tank will be adequate. It is only when people overload tanks with too many or too large a fish for the volume that they have insufficient filtering.

Then there are the toxic substances that no filter can deal with anyway. Pheromones from the fish accumulate and can only be removed by water changes, as can nitrates. All the filtration you could possibly hook up to a tank cannot solve this problem.
