Anyone running a dart closed loop on a 75 gal?
I'm considering running a sequence dart as a closed loop on a 75 gal tank that will house sps corals. Is anyone doing that? I'm concerned about it being too much flow. The tank is the usual 48" long 18" high all glass aquarium. The tank is down now and easy to drill for it. Any thoughts?

I'm thinking of running one on a 46 gallon tank. Depending on the type bulkhead fitting you'll be using you will probably have to drill a 3" or 3 3/4" hole. One of the guys on this board drilled two 1.5" holes and then tee'd them to a 2" line that fed the pump.
I'm planning on connecting it to a OCeans Motions current device. You can throttle back on a ball valve connected to the discharge line if the GPM is too much. Cheers Ordy |

I use one on my 125 to power a closed loop. It does the job very well. Just use the largest PVC you can and reduce it at the tank outputs.

2 inch (up and over) intake. 1.5 inch output up to the tank then to a tee (3/4 into a SCWD) then around the top with 8 3/4 outlets.

I run a dart on my 60 cube and do not have to throttle it back at all.
2" in and 1.5" out, reduced to 4 - 3/4" loc-line nozzles, and it is not too much flow at all. |

Won't have it running soon enough. I spend more time on Ebay looking for deals than I do on my aquarium. The OM Squirt comes in only one version. It's good for upto 1000 gph so installing a bypass line on a Sequence Dart would be mandatory. Probably bypass back to my 20 gallon sump. I've drilled two 1" holes, about 4 inches apart and 3" below the top of the tank to serve as supplies to my sump. If I go with a 3" hole, for a 2" bulkhead, I would keep it high up like my 1" bulkheads. Probably closer to one of the corners. I've been told at least 3 to 4 inches from the corner is good. It I spring a leak I don't have to empty the whole tank. Returns will go over the top with 3/4" pvc reduced from the 1.5" discharge on the Dart to the OM Squirt. Thats the plan anyway. ordy |

I have that basic sized tank, only a bit wider & taller - no problems w/ Dart & CL..................but that would depend on livestock. All softies might be too much, LPS less likely, SPS wouldn't even be close.
I use 2x1.5" drains that join & feed the Dart -> 1.5" ouput to an OM 4 way -> 4 1.5" returns reduced at the tank wall to 1" -> good flow, but too much..............in fact SPS tank & I also have the main return & a pair of Tunze 6000's. Also - my OM 4-way has a "two open drum".

Why buy a pump that large and throttle it? Get a smaller pump or get a larger OM.

Yes, that's correct 6 holes - just as you described.
Flow? Depends - no certanties. In my setup the returns are at the four corners on the back wall. I had the tops pointing along the surface & the lower returns pointing off the wall & forward. Ended up with some dead spots behind the rocks (got filthy back there). Pointed the upper two down along the back wall & added the Tunze = nothing stays to settle. Same here, only run about 700 through the sump - most of the flow is in the tank.
