Nice looking tank there bud

i had noticed that a few had mentioned about the outlet from the return....
I was having a nightmare with mine, combined with the flow from the gyre was creating a vortex (not visible to the eye) along the front wall of the tank and was shifting my sand about to no end....
so i got a push fit /compression T piece from a plumber on site, removed the little nozzle bit of the reefer's out let and with a few wraps of PTFE tape, slipped it into the knuckle. Job done!!! i can still lift it above the water line when doing water changes so it doesn't syphon more than the sump can take and diverts the flow left and right across the back of the tank.
it may look unsightly in these pics, but i can assure you you would think it was made for the reefer's
