just pick up a 125gal tank, stand, filter and everything the other day for $150, ill have to post picks as soon as i get it up and going, ive been doing some resealing on the tank because the build date on the tank is 1985, also i got with it a eheim 2017 canister these filters were suppose to be discontinued back in the 80s amazingly it still works fine, i noticed that the impellor shaft is 2 pieces kinda wierd, anyone know why it has a 2 piece impellor shaft instead of a solid shaft? could i replace the shaft with a solid shaft for a 2217, ive heard that it is basically the same filter.
