red sea max reefer 170 chiller plumbing

[An Bollenessor]

Hi all,

 

I will be replacing my RSM 130d with a RSM 170 to have a sump. I have a coldwater tank so run a chiller, which is currently placed outside the cabinet (behind the back wall, had some holes drilled for tubing). I am unsure how to combine a chiller with a sump (I found an RSM manual online but could not visualise the description!).

 

Do you recommend I have the chiller in a separate loop, with a tube from sump to chiller to return pump to sump? Seems a bit of a waste of energy and also will have two pumps draining a relatively small sump at the same time.

 

Or can I have a tube leave the sump into a chiller, into a return pump and then plump back to the aquarium? Might need a quite powerful pump to pull water through sump then chiller?

 

Any suggestions much appreciated!

 

cheers Mick
