ok so i am on the proses of starting a 110 gallon tank and i currently have a 50 gallon tank and i found a metal halides fixture for a good price and im just wondering if most of the soft corals would make it under the halides for now of course at the bottom of the tank and how high of the tank would the lights need to be

What are the dimensions of the tank? And what is the wattage of the metal halide?

Are you looking at lighting your 50g or the 110g?

150w MH would be good for 50G i would go for 250w if you decide for the 110G since its deeper

A single 250W MH could be placed 12-20 inches above the tank.
The coral would stay where they are, just start the light at 2 feet above the tank.
There is a thing we call "light acclimation". Without light acclimation, coral can get sunburned and easily die. It involves starting with the light higher, then gradually increasing the photoperiod and lowering the light.

what does sunburn mean with coral, does it mean they bleach and die?
