closed loop ?

[slate744]

I just bought a 120 gallon tank that is drill for a closed loop setup. It has a 4" drain with 4 1" returns. Will a mag 12 pump be sufficient for this type of setup?

I would look into the Reeflo line of pumps. I run a dart and love it.

I also use a Reeflow Sapper/Dart Hybrid pump and it is much quieter than most mag pumps I've used.

Wow, it has a 4" drain?
The mag 12 may be a little too small for 4-1" returns.
With head loss and splitting the 1200gph into 4, you might only get 200-250 gph out of each return.

add an Ocean Motion 4-way and use only two outputs at a time...

That would be a awesome way to do it, if you can afford one.
I thought about getting one for my new build, but ran short on cash.

I bought mine used for super cheap... Just got to keep an eye on the sale threads ;) I won't post a price, but it was about 25 - 30% of new so 70 - 75% off...

We also run a Reeflow Dart with OM4. Super quite and low maintenance.
