How high to mount Metal Halide Lights

[Harry_Y]

I ordered a 250w Hamilton Cebu Sun Might Fixture to go over my 180.
My tank is a Mix (LPS, Zoas, Softies, and some SPS)

How High should I mount the light above the aquarium?

Thank you

Congrats! Great fixture and fantastic pricing this weekend with their sale!

You can play with the height. I'd say minimum 10" off the water. A little higher if you can.
14" would probably be a good point to start with and then adjust up or down from there.

mine are 12" above the water line however I have different reflectors. but I agree with d2mini with the 10" min level.
