which aquaball eheim do i have ?

[opal]

Does anyone know which number aquaball eheim i would have for a fishtank 2ft by 1ft. I need to get some new carbon for it and cant remember the model number.
Thanks

doesn't matter which one, the carbon and sponges will fit all of them.

I agree. The beauty of the Eheim Aquaball (I just got one) is that with them being extendable, the pads will all be the same size.
