I am getting ready to setup the wifes 120 gallon tank, her only request is that there are no powerheads showing. So this leaves me to a closed loop.

I plan on using two suctions plumbed to a SCWD and 4 3/4" outlets. If the tank is going to be a mixed reef tank (very few fish) but hard and soft corals what size and brand pump would be the best. The tank has 2 overflows so there will already be two outlets for flow so I figured that 4 more in the closed loop should give me plenty of options.


Thanks for any help

well it really depends on how u will plumb it. Most people like to go with something like a sequence dart since they are dead silent but u have to make sure that u have enough returns to avoid having turbulence or using a valve on the output of the pump to control flow. Just make sure the outputs are nice and wide so u have a lot of movement but with low velocity
