Eheim 600 or Cobalt MJ 900 for Nuvo 8?

[Siejuban]

I am choosing either Eheim 600 or Cobalt MJ 900 to replace the pump of my Nuvo 8, I read most people use these 2 pumps, which one is better?

I use the mj 1200 in my nuvo 16 so my vote is for the cobalt.

Will the MJ 900 or 1200 fit in the Nuvo 8?

I'm not sure how large the compartments are in the back of the Nuvo 8 but I have seen topics on here where the Mj 900 is used in the nuvo 8. Heres an example

Eheim 600

Finally I ordered Eheim 600, since it can be adjust the flow, and easier to set up in Nuvo 8
