    Hi Everyone,
    I have a jbj 28 nano which i just changed over to ai prime hd leds. A few of my zoas dont look happy.

    Water parameters:
    Ammonia- 0
    Nitrite -0
    Nitrate - 5-10 ppm
    Phosphate - 0
    Calc- 400
    Mag- 1200
    Alk- 8.3

    With the new light which im thinking is the issue:
    1) The devils armor (which ive had awhile, hardy as hell), have grown longer, skinnier stalks and different point have pooped zooxanthellate. See pic

    2) a couple are closed like mind blowing palys and rainbow infusion . See pics

    I had my settings for 1st 2 weeks at uv35, vio 55, royal70, blue70, green 0, red 0, and white 30 (total at 24w peak hrs) see pic
    And had it on acclimation mode at 20% and i had 2 screens to filter the light.

    I had assumed i took all the precautions on not overpowering them to the new lights but the zoa poop hints at too much right? Yet the longer skinnier stalks would hint at not enough light im assuming. Any advise would be greatly appreciated.

    I'd try less light first, everything down to 30 percent max. You said primes as in two? That's quite a bit of power depending on height off water. Is lighting the only change you have made? If that doesn't help after a few days you may want to try going higher but I have melted a coral or two with primes lol

    Sry just 1 prime and the zoas range from 19 to 22 inches below the light.

    What was lighting them prior? And what height is the prime above water? Did anything else change ? Acclimation mode cuts the percentage dramatically to start. They may be used to higher light output?

    I had the stock jbj canopy lights which were 25 watts 14k and 1 watt actinic. I currently have the lights on the mount at 9-10 in above the tank.

    I'd go with less light. You've doubled the wattage and it is much more concentrated now with better everything. Lens, leds etc. also may want to ask this in club zoa on here!

    I figured i had the same wattage, light was higher and the 2 screens to diffuse the intensity, plus the acclimation at 20% which i thought was significant. Yet whenever i try to take 1 screen away, some of the zoas take on an umbrella shape. The pooping zoanthellate means too much light right? Yet the development of longer skinnier stalks means too little light i thought. Do they poop if they arent getting enough light?

    When u said reduce to 30, u meant my color spectrum right? 30 across the board? What should i set the acclimation percentage at then?

    I would start at 25% power and work towards the target over the course of a couple months. Increasing 1-2% a week. Just scale down the look you like and gradually ramp up.

    They may want more light? I'd try one way for a few days and if that doesn't work try the opposite

    On the acclimation mode i had the reduction percentage at 20% across and i read it as: example 20% of 40 uv. But reduction percentage i actually want to put it at 80% then it will be 20% output right? If thats true i had my violet, blue and royal at 65-70 and it was only being reduced by 20%. Omg i want to shoot myself if this is correct!

    IMG_1915.JPG So im an idiot im an idiot im an idiot who misintrepreted and reversed the reduction percentage. So hopefully i corrected it time going from 30% reduction to 70% reduction now.

    Zoas like nitrates and phosphates, with newer stronger lights and no nutrients they are probably hungry, my advice get dinner nutrients in the system.

    Yeah my nutrients are low so i give focus feed live phyto everyday, reef roids 2x a week, and feed my fish 3x a day of either cyclopeze or pellets. Should i feed more?
