Help me with water movement please

[BestMomEver]

I'm setting up my new 90 today and will be combining three tanks into it. I have lots of wave makers but it’s kinda a strange mix because they were purchased with separate tanks in mind. I will be combining all of them into the 90 but I want y’alls input on the placement. The tank is roughly 36x24x24. It’s a 90 tall. I plan to put a MP40 on one wall, and MP10 and Tunze nano stream together on the opposite wall and an Icecap 1k gyre on the back. The only problem is I would have to put the magnet for the gyre down in the overflow and I’m not sure I can get my hand in it. The other option would be to put the gyre to the side of the overflow and get a second one for the other side. I prefer as much flow as is possible.

Please give me opinions and/or ideas...

Being a 90 tall I would be putting one of those very low in the tank to help with flow deep and detritus suspension.

You didn’t mention you have a sand bed or not. I think this is the deciding factor in flow , as you want as much as you can without it blowing all over the place. If bare bottom , then options abound . Placement would then depend on your rockwork

Following. I’m filling my 90g today too!! 48x18x24 here. I have a gyre and 2 tunze turbelles...was debating if thats enough flow or not.

I run my tanks with a sand bed. Currently, the gyre is in my 60 about 1/3 off the bottom blowing directly into the rock work. I’m all into balance and stuff, and putting just one gyre on one side of the overflow, without a second on the other side just feels weird. I can get another easily enough but want opinions.

I only have a 20 gallon (IM Nuvo 20)

My sand bed is only 1/2 inch deep and it’s very fine sand particles ( oolite I believe )

I have 5 powerheads at my disposal

2 MP10
2 koralia
1 IM wavemaker

I played around with flow a lot with these powerheads in different configurations .

Any more than 2 powerheads in my system would create a sandstorm of Proportional magnitude to the strength of the powerheads lol

Been siphoning my sand bed with every water change to slowly convert to bare bottom since than

Currently I have 2 MP10 on opposing end with 1 shut off for most of the day. I turn it on a few times a day to move detritus into the water column.

My soft and lps corals like medium flow that is random. I have several sps frags that is almost in front of my MP10 that does great.

The challenge I have is keeping everyone happy as I have a mixed tank. Use your rock rock on where to place your corals and/or powerheads.

Imo....

If all PHs (vortechs or whatnot) are on opposite walls pointed DIRECTLY at each other....you'll get dozens and dozens of random chaotic streams coming off water volume colliding at the midpoint of the tank

A GREAT TEST: is to flood your tank with micro bubbles and tinker with your PHs.... bc you'll see visually the path of all the microbubbles

Have you worked out the flow @BestMomEver?

In my 80 cube(32x24x24) I have 2 mp10's, 2 pp8's, a gyre 230, and random flow generators on my returns.

I like to run them at lower percentages so the pumps last longer(in my mind pushing them 100% all the time will wear out the motors). With that said I run my 2 mp10's on the side glass about half way up on reef crest @ a max of 60%, then my 2 pp8's are at the top on the back glass pointed down @ 60%(run at random times controlled by an apex), then my gyre is on my center overflow firing back and forth @ 45%.

A word of caution on the gyre, the magnets are not very strong. I have mine in my center overflow which consists of glass covered in acrylic, I had to use zip ties to hold the inner magnet in place inside the overflow. They will stay coupled this way, but if I remove the zip ties at about 60% the gyre will fall off the inner magnet(it begins to slide down until it looses the inner magnet).
