270 Gallon Rimless Peninsula Tank Miracles with fish room
- Thread starter kewadiak
- Start date
I had the chance to see this system in person this past weekend. I must say it is impressive. Every aspect is top notch, All I could think when looking at it is, other than a touch of jealous I have to admit, this is professional.
I look forword to seeing it full of corals and fish. Thanks for having me as always.
P.S. I'm still voting for the 2nd razor.

Sweet build. Any updates?
thank you yes I will update soon with more pics

Okay from what I have been reading is the new thing in flow is to create a Gyre and random flow is the old way of doing things with a closed loop. My closed loop has 8 nozzles that alternate off of 2 ocean motions. With this tank being a Peninsula and I do not want power heads how do I create a Gyre and my returns always flow to the opposite side of the tank?

This stuff is not really all that new. It was suggested several years ago but not very well explained.
Do you understand what a gyre is? It is a circular motion of the water flow all the way round the tank. This can be parallel to the sides, i.e. the water moves left to right along the front pane and right to left along the back pane. Or it could be a bottom to top flow that pushes up the front pane and down the back pane.
These are just examples to get you thinking. What you don't want is an area of dead water in the centre of the tank, so you need to break it up a bit. People usually add some random movement to keep from just having a laminar current moving around the tank in a straight line. You can also put your Ocean Motions on a timed controller so that you reverse the gyre every six hours like the tides.

Yes i kinda understand but the only thing is with the returns at the top of the tank they are always gonna push water Left to right at the surface so i will never be able to create that switch direction of flow right to left? I was thinking of removing the ocean motions and positioning 4 nozzles in one direction and 4 in another and just alternating the pump on a timer. It sucks i just spent 1000 on the ocean and motions but i want the best flow possible and thats what i tired to create with the random flow?

Why wouldn't you connect the first Ocean Motion to the first and third bottom nozzle in the front and back, and the second Ocean to the second and fourth bottom nozzle in the front and back.
Aim the first and third bottom nozzle in the front to go from left to right and in the back to go from left to right. Aim the second and fourth bottom nozzle to go from right to left and the back bottom second and fourth nozzle to go from right to left.
Then you could alternate between one Ocean Motion running for a while and then the second Ocean Motion running for a while. Make sure you have penductors on all your bottom nozzles to get the most flow out of each.

yes that sounds good i guess i was thinking i needed a circler motion of flow like if you were making a whirlpool one way then reversing the whirlpool. in my case i would be pushing flow front to back then back to front. I do have the penductors for those but they are gigantic looking in the tank.

They are directly under the overflow box two 1 1/2 drains post # 75 you can kinda see

I understand I just was gonna try not to re plumb everything. With the tank being a rimless and the close loop pumps being fully open it actually boils the water right out of the tank.

Great start, I would probably be unhappy with those seams as well if I spent that kind of money on a custom built tank.
