plumbing question

[dkelly]

I'm adding a 1/2HP chiller to my 210g and need some suggestions on how to plumb it in. The chiller has 1" threaded PVC connections.

Current setup:
72" acrylic sump with multiple bulkheads
<ul>
<li>1\" bulkhead for return and 2x 1\" drains</li>
<li>1\" & 1.5\" bulkheads for skimmer</li>
<li>http://www.superskimmer.com/72_Sump.htm">http://www.superskimmer.com/72_Sump.htm</a></li>
<li>Blueline 30HD-X pump (max 1110gph) connected from 1\" bulkhead to Y with 2x 3/4\" returns</li>
<li>[IMG]http://www.bluelineaquatics.com/products/water_pump/hd.html">http://www.bluelineaquatics.com/products/water_pump/hd.html</a></li>
<li>magdrive connected to a Coralife UV returning to the skimmer section of sump</li>
</ul>
ETSS 800XR external skimmer driven by a Blueline 55HD pump

Ideally I'd like to get rid of the magdrive in the sump and plumb the chiller and UV so that they drive both 3/4" returns. I don't mind breaking down the sump to drill additional bulkheads if required.

I teed off the return with PVC and ball valve then reduced that to 3/4 flex line into chiller. 3/4 flex line out of chiller ran back into the sump or you could run the chilled water back directly into the tank.

I like to have the output of the UV go directly into the skimmer. So anything killed by the UV can be skimmed out immediately instead of having dead microbes floating about. My skimmer output is then fed through my filter sock to get any other particulate matter.

What is the manufacturer suggested flow rate through your chiller? If you can handle the head drop, I would run your return though the chiller and get an external pump to feed your UV and then skimmer.... I have a sepatate pump for my chiller but I would have prefered to plumb it into my returns...

My chiller recommends 750gph minimum/1500 gph maximum

 

[schwaggs]

seems like placing the chiller in line with your returns would work...

Wouldn't that flow be way too fast for a UV? I would think that the chiller efficiency would go down also the higher the rate of flow.
