I'm in the process of setting up my 72x22x20 peninsula and have opted for the following:
Keep in mind that once I place corals from my two other tanks into this one, I will probably change all this as I see the flow patterns.
Also note that I have eurobrace and armoured seams, so I can run a high water line with a standing wave pattern without spilling water, this to me is the best reason to get eurobrace and avoid rimless.
Photos below of placement
2x DMP 30's on ghost overflow end (should of upsized to 40+ for the stronger magnet)
2x Nozzle return (
1x DCP-10,000 set at 57 power) - bean animal overflow
1x MCP-180 gyre opposite overflow
My gyre creates 3 different standing wave patterns throughout the day based on the tank resonate pattern.
1- overnight long wave (72 frequency, 57% flow) starting 9pm to 6am
2- day time mid wave (48 frequency, 75% flow) 6am to 3pm
3- day to night shortest wave (36 frequency, 72% flow) 3pm to 9pm
2x DMP 30's are set to run constant and random against each other, placed 1x higher (hence superior) and 1x lower (inferior) on the ghost overflow side. I do not like to run my Jebao's at 100%, with two exceptions, first being random mode they can go to 100% (and nutrient export mode explained below), on constant they only go to 72%, its the sweet spot I've found for noise and longevity.
1x DCP-10,000 runs 57% and the two nozzles push the water against the glass and down, being carried by the DMP's to the far side of the tank. The locline is arched up to help with a siphon break. Chose not to go with random flow nozzles as I like a sheet of water to glide down the glass and be less interference against the gyre's wave motions.
I do have some filter floss in the overflow to help absorb the crash of the standing waves, I dont mind the noise, and after a while you learn its sound pattern/behaviour and it becomes a warning signal if something isn't working right. Plus its rhythmic, I am training myself to imagine its water lapping up on the shore.
1 nutrient export time where everything goes to constant 100% (all 3 in tank pumps, not the return) for 8mins at (6am) and I'll add an additional export window at 6pm based on some autofeeder timing, although I love to feed my fish frozen by hand as its a joy to watch.
