AI Sol upgrade to Hydra 54

[evan1017]

Has anyone thought about buying the $299.99 upgrade kit for Sol to Hydra 54???

other than wattage and full spectrum, what about the light spread? cause the 3 Sol over the 6' long and 24" tall tank which seems not enough coverage in between. Plus, I can't put any acropora below the middle level....

I wonder, does anyone know what's the life span of Sol?? obviously, it doesn't last forever..... I have been running it for about 3 years with apex controller, it also mean I can't use the apex anymore once it upgraded and another 100 bucks for the AI controller.....
