led lighting

[tgditz]

I am looking at purchasing a 180 gallon tank for saltwater, I have 3 125w led lights, will that be enough or do I need stronger lighting?

I used 3 x d2120 with 90 degree optics over my 180g mixed reef I hung them about 12" off the water and there still is some shading because the tank is 24"wide lights are about 16"x9".... you could use 4 lights and turn them the other way above the tank, if you want an sps tank I would....

but again 3 was plenty for a mixed reef

Yup, that outta do it.
