Zoas don't need much light. If you plan sps or lps, then I recommend an apogee par meter. When you get coral, find out the par and flow where the specimen grew. The, place accordingly in your tank. Par changes significantly in a tank lit by led's. Even within proximity of inches the par will have large disparity due to the directional attributes of led's and the shading of rock work and coral. The par meter takes the guesswork out.
Start with the following ratio: blue 87, deep blue 83, red 12, green 21, uv 25, white 40, violet 60. Measure par and adjust accordingly.
