That is a Totally AWSOME closed loop. Got a web site with pics of the front? I have considered drilling my tank and getting the 4 way ocean motion. Where is the intake?Fly Guy said:In a nutshell the closed loop providesextra flow and water turnover in the tank without having to route it through the sump or having to use powerheads. If done right it can elininate more clutter in the tank and still achieve more "true" reef like flow. I just built what i believe to be a great closed loop...its a little on the extreme side.....but i like it
every pipe you see there with the exception of the one going across the top is for the CLS.
There are ZERO pipes in the tank with the exception of the spraybars.....
i havent done the math for head loss.......OH GEOFF..need geoff for that...............anyway..running a barracuda on the OM 8-way and a dart on the return........so 8100 - head. This is a LPS only tank. with omniflex nozzles on each of the returns i can totally direct where i want the current to be and where i dont want it to be. Some mushrooms and such obviously wouldnt appreciate that flow.....three90s&125sump said:How many GPH are you pumping in that thing fly.
I can't wait untill I get my 800 cube.

AS far as the head pressure thing goes....i dont think there is anything gained by gravity feeding into a pump like that....so you still have to lift the water up to the hub.........wheres geoff???
I defintely DO know there IS loss to friction from splitting a 1 1/2" line into a 8 way hub with 4 ports opening and closing every 15 seconds.....and then up to the cls outlets
regardless...nothing a big enough pump cant compensate for
go chiller.......with built in controller and heater outletwtrguy said:valves / elbos / tees / all of that will cut down the flow, as well as head distence. but there is always a biger pump. i am running a mag 36 on the sump outside. it moves the water to the 125 about 9' head i think i move about 1,200 gallons per hr, BUT that thing is the noisest thing it sounds like a rock crusher, it is going soon, torn between the chiller or the pump.
