Lets talk closed loops....

[pistonkev]

Hey I have been away for over a year building a house raising three kids Yada Yada Yada. Anyway setting up a new 180 in wall tank and I want to run a closed loop. There used to be a cool closed loop thread over at reef central. It's gone with all the other Calfo posts not sure what happened. Anyway I am looking for the right size pump to drive that closed loop Do you think a Iwaki MD100RLT Water Pump will do the trick without trowing too much heat into a 180? How many heads should I have coming off of it for flow 12 or more?

for a 180, you can use a hammerhead. I use a Dart on my 125 and have 3 returns split into 6 returns using 3/4" loc line.

Is that all you are using for flow? What are you keeping? SPS ??

Hammerhead rocks! Low heat, low noise, lots of flow! Many pics of CL designs and articles with Q & A from other reefers on wetwebmedia.com. That's where the "Calfo Manifold" design is for example, and is what I use.

Yep, I have a small pump that is a return from my fuge/sump but it just makes the surface of the water move to break up scum. I keep a mixed tank, one side is SPS the other Softies and LPS.

Sequence makes & nice pump, I also agree on the hammerhead, also if you want switching flow I would consider an Oceans Motion or a MBV! I love the MBV, it rocks!

I don't know if I'd call the Hammerhead quiet. It's a great pump and I have two under the house, but I wouldn't want them in my living room -- especially if you have to throttle them back at all.
