    Hydras not going lower then 15 %

    Yesterday for some reason my apex power failed now tonight my moon lights wont go on for either my frag tank or my main tank. i pulled the aqua buss cables out and plugged them back in but the lights still wont go on. For moon lights i have it at Violet 1, Deep Blue 5, Royal Blue 5 and UV 3. I tried playing around with the other settings daylight ect and they all work fine its just the moon thats giving me a problem. If i raise any of the colors to 15 it will work but below that it wont any ideas??

    Thanks!

    The color * overall intensity must be > = 100 in order for the Hydra LED's to illuminate.

    So for example, if a color was 1 and the overall was 100, you're good.

    If a color was 5 and the overall was 20, you're good.

    If a color was 5 and the overall was 10....well, in a word, not so good.

    So for me, I use just the Violet as moonlight, set to 100 but my overall is 1 and they work just fine.

    That sounds like really terrible engineering to me. Thank god I didnt decide to throw another 200 per light to get those instead of the Onyx leds. Disaster averted.

    Those should light.

    Try a quick test and just flip it around - set a color (any one, doesn't matter) to 100 and the overall to 1. See if the LED lights up. Make sure the outlet is in AUTO.

    Actually, it works quite well. The combination of the color-specific intensities and the overall start and end (of ramp) intensity values allows for a far greater degree of flexibility than just color specific or overall intensity settings alone.

    Another way of looking at it is that the effective intensity for a given color channel is a % of a %. That final value must be =>1 for the LEDs of that color channel to come on. Anything less than 1 is effectively a zero % intensity.

    If I put any color to 100
    it will work( I tried different numbers to see what was going on) but under 15 won't work. The outlet is set to auto ( and I just tried on for the heck of it and it wasn't working )?

    I agree. I too am using Russ's season table and my hydra 52 will not light below 4% for LED Moon. See attached pictures. But yet for LED Night, this seems to work fine and the LEDs light up. How bizarre? Any ideas? I've tried swapping the intensity to 1 and the colour on the light to 100 and the same result, it won't light below 4.






    Thanks for your help.
