Chiller installation plumbing ?

Hey everyone. I am going to get ready to install my aqua medic chiller that I acquired from a local reefer. I recently built a manifold for all equipment but since I started running 2 reactors I don't have any more excess flow that I can run through the remaining valve that I have.
I have a quiet one 4000 pump and I can use it to provide flow through the chiller but where should I draw the water from? Should the water be drawn directly from the DT and back to the Dt? I was thinking that I should plumb the chillers return straight to the tank but I don't want to draw from the sump to the chiller and then back to the tank. That would be 2 pumps returning water to the DT. Would it be ok the draw from the sump (skimmer section) back to the return section of the sump?
I apologize for all the confusion and I hope I was clear enough. Thank you for your time.

 

Just for your information the chiller is a aqua-medics-hcl-1200chb
Believe it's a Titan 2000, flow rate is approx. 528-1056 gph.

 

I use an aquaone artic 1/6 HP chiller. I draw my water from the return section and return it to the return section. Over all it doesn't matter as eventually the water will be cooled. My tank stays constantly 25.5 degrees celicius. Cheering.

 

Your idea is fine...draw from one end of the sump to your pump bay unless you want to return the chilled water directly to your DT.

Drawing water from the pump bay and returning it to the pump bay will actually make the chiller work a bit harder, as you'll be dealing with water that has been warmed by two pumps (assuming the chiller feed and main return pumps are both submersible), and thus, pulling the water down farther to reach your desired temp.

I'd get a smaller pump than the QO 4000 to drive the chiller, esp. since you won't be pumping against any head...something on the order of 500 gph should be fine, based on your chiller specs. A smaller pump will add less heat to the system as well.

Greg, thanks for the advise. So, I run a little giant that is external, the qo 4000 can also be run externally. I was planning on adding a valve to the qo 400 to reduce the flow (is this not a good idea, remembering a conversation that it was better on a pump if it was dialed down a little.)
I was thinking of drawing water from the skimmer section (thinking of just submerging the qo 4000) and having it drop into the return section of the sump. How does that sound. Does that kind of jive with your response? I think I was reading and trying to visualize in my head and that is what I came up with through my mental troubleshooting.

 

This is what I was just thinking of doing. Thank you for the help.

 

Make sure you run good water through chiller as it will build up in time & clog the chiller. You want water to run through it slow so it chills more.

 

Ok so water in the skimmer section has already been filtered so that would work right. ?

 

You'll be fine. I really wouldn't worry about the whole "filtered water" thing...it's not like you have huge chunks of junk in the water column of your sump. I've never, ever had a chiller clog up, and at one time, we were running six of them.

Valving the QO down to where you want it is no problem...I was just thinking that if you're tight on room, as many sumps are, you can get away with a smaller pump.

 

Thanks Greg, that helps. I am a little tight on room but I think I can figure something out. If I have to run the QO dry I can and just have a piece of PVC going into the sump. The only problem I've had with the QO is that sometimes it has to be jump started and I won't be able to do that with the pump in the dry. None the less, all the information has been helpful and I appreciate it. Thank you for your time.
