AI Hydra 52 or Kessil a360we???

[ReefBoy]

As you can see I currently have 2 Kessil a 150's ofr my tank but I have barely gotten any growth over the past year.

TIME FOR THE UPGRADE

I want those awesome purplish colors that some people are able to achieve while the red corals in the tank still pop. You get the gist right?

Tank Dimensions: 60x18x24.
My biggest problem with the Hydra is the mounting...
My tank is already filled with water and it is about 3inches from the wall behind it.
IF I got the Hydra. could I mount it on the left and right side of the tank using the EXT tank mounts? Is it adjustable in any way??

With the Kessil I can use the Goosenecks I already have, to mount the 360we's the same way that the 150's are setup..

ANY SUGGESTIONS ARE GREATLY APPRECIATED!!

I don't know if they can be mounted from the side. that would look strange
