    Hi there:1:

    I need some advice on setting my led light times please. Any suggestions and advice will be appreciated:

    I bought the intellisun led unit (85w) for my 60cm cube. I had a T5 quad unit which operated with a diy timer. Lights on were at 10:00am and lights off at 10:00pm.

    There's three phases available; blue, actinic and purple plus. The three phases can be individually set on hourly intervals from 0% to 100% intensity.

    1. What intensity % do I start with in order not to shock the corals?
    2. What time should they go on in the morning?
    3. What time is best to go off at night?

    There is an option for sunrise and sunset as well.

    What do the pro's recommend for optimal conditions.

    Ps. I have softies, lps and one monti sps frag.

    I would keep the times the same. Fade in / out over 90 mins or so. I would start off with a max of 50 - 60% for a few days and see how the corals react. Then you can increase the max intensity by a percent or two each day or a couple every 2 - 3 days.

    @theresacloete , you are just about too fast for me, I'm currently in a discussion with reefers that are making some amazing things happen with their settings on their intellisun's.

    For now I'm sharing an American Reefers (formulated, not thumb sucking but actually measurements at 19 deg Lattitude) setting he shared with us, I will be providing much more detail later :) for now I urge you to use this and let me know how it goes.

    Thank you @Andre@ReefAquatics I will try the settings. When looking at the diagram it makes sense to do it that way.

    Will keep you posted.

    This setting is recommend but only after you have acclimated your tank.

    Of course. I started acclimating the corals on Thursday. Max light intensity at the moment is 45%. I will gradually increase on a weekly basis untill I get to 100% at midday.

    Thanks @Andre@ReefAquatics for the advice.
