Shallow reef tank wavemaker sizing/type

Uzair Aiman · Sep 18, 2025

Hello R2R community!
I’m currently planning on starting my new tank
120(L)x45(W)x30(H)cm // 2x1.5x1ft (~40gallons)
And I’ve been thinking of the type of wavemaker to use in this type of tank.

I was thinking of having 1 gyre wavemaker at the end (I am planning to have 3 viewing angles , as the aquarium is going to be sort of a “divider” between two room spaces) but I’m not sure if it’s sufficient enough in creating flow.

Or should I just use 2 of the conventional wavemakers, placed opposite sides of the tank (which will ruin the aesthetic, running a cable through one side of the tank as it’s a divider).

So, I’d like to know if it’s possible to just use one gyre wavemaker, heck even if it’s possible to use just one normal wavemaker, and it’s appropriate sizing.
Thanks in advance,
Uje.

in my frag tank (48"L x 24"W x 12"D) I use one gyre on each short end, slightly offset front to back, on the bottom of the glass. I absolutely love the flow it creates, as do my corals. It encourages growth and prevents settling of detritus.

In a tank your side, one gyre would do the trick for sure, and if it's a bare bottom tank, you'll want to mount it nice and low on the glass. I use and recommend Hygger gyres, because they are affordable, the controller is easy to use, and they are easy to take apart for cleaning and maintenance:

The chaotic, widespread and gentle nature of the flow created by gyres is, in my opnion and experience, superior to that of "puck" shaped wavemakers. I even prefer gyre flow to that of vortech pumps, which I also own and use, which are far more expensive. The only downside to gyres is a larger in-tank footprint.
