How many inches from the surface of the water should I hang my 400w CoralVue Lumen Bright and which Pendant should I buy the smaller one or the larger one? I have a 220 gallon fish tank 30 inches high.

From what I have read about those reflectors most people recomend 14 inches to get a good spread of light from them. They seem to be pretty focused any lower.

Ive got my bulbs 14" off the water. Ive got the minis, the larger ones may give you more spread.
