Unknown Eheim Canister Q's??

  • We are currently upgrading MFK. thanks! -neo
If you do that, you will get more flow but I highly doubt you will get over 800 GPH.

Reason is, those pumps are rated at Zero Head Pressure and without any restriction.

The "T" fitting will add more restriction in flow to the suction side of the pumps which is not good. You are better off finding a Wye to reduce and chance of pressure drops on the suction side.

The pipe/fitting diameter used on the filter will also cause some restriction since they are only designed for a certain range in flow.

There would be no problem doing what you are saying, I would just find a Wye and a few barbed fittings. Im going to guess the output of that filter has 5/8" fittings and so do the pumps? PVCFittings.com has some good TRUE WYE adaptors. You will need barbed fittings too.

You say the piping is 1" ID, is this the case for both input and output? The 2260 has 1" input and 5/8" output.
 
So do you need to remove the Bio media to get to the Mechanical Media?

This is the father of the Eheim 2260. Lots of simularity. 2260 has a 4.8 Gallon filtration volume. I would says its an early model of the 2260

To find out its filtration volume, measure the depth of the filtration area only and the internal diameter of the canister.
Volume = (Diameter / 2) * Radius squared * 3.14 * Filtration Depth

11" diameter canister with a 14" filtration depth

Example, 11/2 = 5.5 * 5.5 = 30.25 * 3.14 = 95 sq/in * 14 = 1330 cubic inches = 21 Liters of filtration volume or 5.75 Gallons.
I would like to know the filtration volume to see if its the same as the 2260.

You can find calculators and conversions here

Exactly. In order to run both pumps on the output you would need to modify the output and input diameters to accomodate that much flow.

OP, you could probubly upgrade the pump with a 2262 pump because the 2260 can be adapted with the 2262 pump and get a 900 GPH flow rate at zero head with all the same pipe diameters.

I measued the canister,..goes like this,..depth is 14''
and diameter is 11 3/4 inside. So it's pretty much
the same as yours,..

Can i just tee the output on top of the canister to
run both pumps and let gravity fill it? All plumbing
on this is 1'' i.d,..trying to get the most out of this
filter,..

Hooking this filter up to my 90gal for now,..it's a
drilled tank w/ overflow box inside it,..need to save
some $$ to get the 250gal up and running,..

Wow, I don't even own a 2260, I just used those random numbers as an estimate. Im pretty darn good !!! haha. Im going to guess that the filtration volume ends 1" below the top of the canister and 1" above the bottom of the canister. Which would give you a 12" depth which means there is a filtration volume of roughly 5.63 gallons. Thats A LOT!!! I would like to know the depth of the bio media.

Answer to you next question is 3 posts up. :)

I see what your saying,..input on this is 1'' i.d and the
output is 3/4'' i.d,.. but i pushed on some 3/4 hose
to the out put , cut it flush and pushed over the 1''
hose for a tight fit,..so now it's 1'' in & out,..or should
i not do that,..
 
Wow, that's a retro classic eheim canister and a good one too. I remember seeing those from my fathers monster fish tanks back in the 70's. Great find.

Haha,..good guess then:) well far as volume,..i
measured inside acroos to get 11 3/4'' and depth
inside to the side for 14'',..hope this helps,..heres
a couple pics of the inside,..bear w/ me, it needs
cleaned:) As far as depth of bio,..the filter is empty.

Well, according to the diagram you provided, please remember I have never seen this filter in person, It looks like the input is at the bottom and the output is at the top which means the mechanical media is at the bottom and the bio media is at the top. Which also means, you need to remove the bio media to get access to the mechanical media to clean it. Right?

Are there any baskets which allow you to remove media easily?

I see what your saying,..input on this is 1'' i.d and the
output is 3/4'' i.d,.. but i pushed on some 3/4 hose
to the out put , cut it flush and pushed over the 1''
hose for a tight fit,..so now it's 1'' in & out,..or should
i not do that,..

Bad Idea, if you clamp the hoses hard enough they may not pop off but it seems like an issue waiting to happen.

3/4" output, means the input of the "pump" must be 3/4 too right? Remember, im figuring this out from pictures and common knowledge.

If the pump has a 3/4" input and filter has a 3/4 output than increasing the piping to 1" is not going to do anything positive.

Basically, you would have both pumps connected to a 3/4" TRUE Wye (there is a difference between a "wye" and a "true wye") which would be connected to the filter. Then on the discharge side of the pumps you would run a 3/4" like each to the tank so you have two outputs. I wouldn't try merging the outputs together.
