Eheim 2213.Removing the media basket to increase media capacity.

[lescarpentier]

The 2213 is the only filter in the Classic line that is provided with a media basket.I found that the basket actually made the servicing of this filter more difficult than my much larger 2217.After I noticed snails between the basket and the outer canister I knew that at least some water was bypassing the filter media,so I made the decision to eliminate the basket.

Lattice screens,part # 7273050,are available to make this conversion,however I found them a little difficult to find,and in limited supply.Another alternative is to purchase lattice screens for the 2215,part # 7274050,and remove the outer ring on the screen to produce a carbon copy of part # 7273050.

Unfortunately,once the basket is eliminated,the filter pads from the 2213 will no longer fit the filter,and the correct size is not available.I overcame this problem simply by using a fine filter pad for a 2217,which is thicker anyway,and trimming it down to the correct size.I was able to save the course pad by using the scrap from the fine pad to fill in the extra space around the course pad.

The course pad,and an illustration of the additional space.


My remedy


Before adding the additional media.




The most significant benefit of removing the basket is the .7 liter of increased media capacity(25%)that the removal of the basket provides.I made use of this extra space by adding 3 cups of Ehfisubstrat to the original 2 1/2.

Thanks for this, les. keep this type of stuff coming, as you seem to be able to make a really good product even better with little to no effort involved. Plus, this (and the other "experiments" you're doing) is a great resource for anyone trying to maximize their eheim's efficiency.

Maybe a little bypass is good and keeps the flowrate up?

It doesn't work that way.Bypass has absolutely no bearing on the flow rate of this filter.

It would seem that total flow rate would be equal to
(1) flow rate through media
+
(2)flow rate around media, otherwise called bypass.

In a filter which has zero bypass, flow rate will decrease as media clogs.
In a filter which has some bypass (2) might actually rise as (1) decreases due to clogging, this is in fact what happens with the oil filter on your car as its pores gradually clog, and it is intended to work that way, as dirty oil circulating is still better than no oil circulating.

More media capacity could be a good thing, though, and it would be interesting to determine if the larger capacity now allows that particular filter to be used on a larger tank, or if the 116 gph flow rate determines the maximum size tank on which it can be used.

I find that hard to believe.

Would anyone like to have some 2213 lattices like lescarpentier mentions?

Eheim support told me that you can use the 2215 Classic or ECCO pads with the 2213 lattices.

You need 2 of the 2213 lattices for the conversion. PetBlvd.com has 4 left at $3.29 each plus shipping. http://www.petblvd.com/cgi-bin/pb/EH...ml?id=LsgArYJS

I found mine here. Got them yesterday. The packaging was old and dusty but then I'm sure it's not one of their most popular items. Don't know how many they have in stock. Give it a try

[Rev2eight]

I order them yesterday from here: http://www.pets-warehouse.com/
I hope they come through cause ive never had any experiences ordering from them.

I ordered mine off Pet Blvd too and they came. They look really nice.
Do the 2215 classic pads fit exactly, or do you have to cut them down still?

Dang! I was at the Post Office when UPS came by. He might come back later.

I'll let you know when I get my order. My lattice screens and 2215 pads are in this shipment.

They must be trimmed.
Don't forget that with the space you recover you will need about 3 cups of media to fill it.

Hi

I just received my lattice screens and the 2215 sponges. The 2213 filter ID is 5½" and the 2215 sponges have a 6¼" OD.

I don't think that you need to trim the 2215 coarse pad at all, but that's a guess. It fits fine and it forms a nice, snug seal without any creases at all. It is very compressible. You are compressing it around 13.6%. Will this make it too compressed and slow the flow substantially?

The 2215 fine sponge isn't nearly as compressible as the coarse sponge is. When you press it in, the edges of the fine sponge want to turn up some. You also get some small creases formed, but they can easily be smoothed out. It might need a slight trim before use.

My 2213 is new and it might be a little while before I will be able to check it out. I might want to see how much it flows with the media basket before I change it over to the 2213 lattices and the 2215 sponges.

What is everyone else doing?

I ran across a new in the box 2011 from an estate sale. I can always use the 2213 sponges in it. Hum ...

PS: Have you guys seen the ECCO Pro? It comes in 3 sizes and it has a prefilter:

I haven't seen this one yet,but the rating for aquarium size looks drastically over optimistic.It looks like a regular Ecco to me.

Judging by the photo on the box,I think that the pre filter is nothing more than a sponge in the first tray.I think that they may be phasing out the pro II series..

Phasing out the Pro II series. That's bad. I have a new 2028 that I haven't ever used. I bought it 2 or 3 years ago.
