Got a chiller, but I think I missed something.

So I'm new, and still figuring stuff out, so over the past week it got hot and that prompted me to buy a chiller. I haven't gone home to look over the parts yet but.... I think I need a pump.

If I do need a pump, which pump would you all recommend, the chiller is a jbj 1/15 and I bought the install kit as well, which comes with tubes and what not.

Or maybe I'm wrong and the chiller comes with a pump?
 
Yep. You need a pump. Some people run their return line through them. Thus it would go from sump through the cuiller and then to the tank.

All a chiller does is cool the water as it passes through it. You need something to run the water through it. You don't, however, want to push water through it too fast or it won't get the desired effect.
 
So I have the JBJ NC 28, it has two Accella pumps, did you mean, run the line from one of those pumps to the chiller? and from the chiller back into the tank?
 
That would work.


(Bryan, are you sure about your comment on water speed?
beware!!!
Without invoking funky mathematical equations to calculate flow variations on the thermal gradients across the barrier between the water and refrigerant, and assuming the thermal load of the pump is the same, it shouldn't matter how fast the water flows through. Yes, it matters on the water output temperature, but it shouldn't matter on the net tank temperature

ie, if you flow water at twice the speed, the temperature differential gets cut in half


)
 
Yep Exactly. Picture your return line going from the sump to the tank. Essentially what you would do is cut the return line coming out of the sump and plumb it to the inlet into the chiller. Then plumb from the outlet of the chiller back to the tank.

I will see if I can get a pic up to show you better.
 
Pretty sure Tony. (Damn I wish this would give the someone has posted while you were replying message). I do know in my case I actually run from my sump throught the chiller into my fuge and frag tank because of both the force coming out of my tank return line and the head loss it would put on it.

Needless to say I used to run a Mag 7 in my old 58 from the sump underneath the tank through the chiller ( a 1/10 JBJ Artica) and back up to the tank without issue and that was in Texas when we would hit 100's on a very regular basis during the summers.
 
Ok crappy picture time

Read the instructions, chillers have a minimum recommended gph you should put to it. Make sure your pump fits that requirement.
 
Yea definately do not over or under drive the chillers requirerments for the recomended flow, too fast and the tank won't cool, too slow and the tank won't cool...................understand?
 
So I'm back to the "what pump would you recommend" question. The chiller is 1/15 and it says flowrate 110-160 gph in the manual. My stock pumps (powerheads) are 266 gph but were not strong enough to push the water through. Because my tank doesn't have room, in the back for another pump, I think I need to go external.
 
Don't want to hijack your thread, but i was kind of wondering the same thing. I was thinking of running my chiller from the overflow from my frag tank and then back to my sump. But if that won't work i was thinking of using a eheim 1048.
 
Your stock pumps are rated for zero head height and zero restriction. perhaps you can upgrade your internal powerhead based pump for something a bit stronger?


BTW, was there zero flow through the chiller? If so, that sounds suspect.
 
yea, I was watching the pipes, water went into the chiller, and would almost make it back to the top. It just didn't quite make it.
 
then all you need to do is upgrade the powerhead :) Perhaps to an MP1200? They have a head height of 69". They are inexpensive and reliable.
 
I was thinking about taking a trip down the Aquarium Showroom tomorrow, I'll see what see they have.

Thanks for the suggestion :)
