    HI I'm new to the site-- just a beginner really although I had a reef tank a long time ago-- 15 years ago actually!! We only had bulbs light back then -- no LED's. My question is this-- I restarted my tank about 6 months ago and am trying to learn it all over again. I do have LED's now( my wife found some chinese knock-offs on the net) They have been working great it seems-- everything is really growing well-- esp several hard corals . My problem is several of my zoo colonies are losing their color-- they have been bright orangefor the past 4-5 months and beautiful but all of a sudden they are getting kind of an ugly dark brownish color and turning a whitish color centrally?? I haven't changed anything in the tank and it seems like it just started about 2 weeks ago?? I have some up close to the surface and some close the the bottom and they are are doing the same thing?? I started using Red Sea Reef Energy Part A and B about the time it started happening( maybe I'm imagining that though?) Otherwise they seem really healthy and continue to grow and expand onto the adjacent rocks. What do you guys and girls think?? Should I try just keeping my blue lights on for a few weeks? Thanks for any help.

    that acclimation is VERY fast. Most recomend starting at 30% and ramping them up 5-10% a week. but its now been a month, how's it all looking?

    Agreed! Does take LEDs a while to get dialed in, but when you do... Sweetness!!! Finally have mine at 100% blues and 60% whites and all is gravy. Did have an initial issue like you did and lowered it way down, but the partially bleached corals eventually all came back

    I understand acclimating existing corals to the light but when you add new corals to your system are you guys starting the cycle over? Or do you even have an issue with the new corals?

    The idea would be to put them down on the bottom of the tank and in a area with shade if possible unless they came from a tank with leds. Then you would try and find out what intensity the leds were set at and place the new corals accordingly.
    I just bought a bunch of zoanthid frags (16-17) and redid a short 2 week acclimation program with my Radion

    Oh ok that makes sense. I've always wondered what to do. I just got my LEDs and when I buy corals I wasn't sure how to treat it. Thanks for the info!
