Need help on oowerheads for a peninsula tank

[Reefara]

Yes. The picture you sent with the tank. I assumed that was your 240. Lights and tank look really good
You like the dmp powerheads better than the gyres?

Giesemann Spectra (250w on DIY magnetic ballasts)

these are the lights he is using btw

Not sure if you answered the question. 2 jebao gyres or I believe you said 3 dp40’s?
I like the lights but I prefer LED’s. I contemplated adding t5 but I’m not into sps like that

yeah werent you looking for wavemakers??
you can go the route with 2 jebaos gyres (link is there) or 3 dp40's (link is there)
IMO id go with the gyres

for the lights i sent what he is using which it was the Giesemann Spectra (250w on DIY magnetic ballasts)

t5's are all around the best lights to grow any type of coral... they are superior no matter what you want to grow

The tank picture posted is my OLD 250g tank. It ran 6 Radion XR15 Pros and 1 AI Blade. I ran 2 Vortech MP60s

My NEW tank is a 100ish gallons and runs halides. I have an Orca 6075 and a regular 6075. I am replacing the regular 6075 with an orca 6105 which is likely too large but we will see.

Return pumps should never be figured into the flow IMO especially in larger tanks

Appreciate you hopping in and helping. I’m not ready to run halides. I wanna keep it simple as I can. T5’s and leds

Im running 4 jebaos on mine. 60x28x18. 2 Dmp 40s, a slw40 and the jebao gyre. Im pretty dang happy with it. Absolutely no dead spots in my tank, running all pumps at aboyt 70%. If anything get rid of the gyre and slw40 and add another dmp40.

Just got a new 90x36x24 peninsula.
My thought is having two gyres pushing down one long side. one gyre pushing toward the overflow box(36x24x6 and two mp40;s pushing up from the bottom of the tank.
Gonna make the stand with two small openings for the dry part to be place on the bottom of the tank inside the stand...
Kinda like a closed loop idea..

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.
