    For Freshwater PAR levels please click here.

    The list below shows the light ranges needed for coral growth.

    The minimum figures are used as a giude line where growth will be minimal and the health of the coral may come into question.

    At the maximum level no more growth will occur for an increase in light.

    Remember PAR is a better measurement of quantity of light than quality.

    A seneye  reef device will help you do more analysis than just PAR.

    You can find more information on Aquarium lighting here.
