    Hi chalice experts,

    I want to get some advise on the chalice light intensity . Currently I'm switching to a hydra 26 for my nano tank. As I have different type of chalice (rainbow, pink bobbies, mummy eye ), I want to know what is the best par level for them. Before I kept them around 70 to 80 par, they are doing okay and kept their color but their color seems to fade a little (not as pop as I first get it) after they have been in the tank for a while. Is it because I'm using led not t5? What is the maximum par I can keep them as well?(because I have a mixed reef and the sps on top of the tank might need more light). Thank you!

    From my experience (Which isn't alot lol ) chalice's should be around 80-100 par. Hope this helps!

    Thanks. Will over 100 par affect the color or health?

    if you slowly acclimate them to it they should be ok, just keep a close eye on them.

    Along with light, really stable chemistry is a must for keeping chalices healthy and colorful.

    True. However still need some chalice experts on their light with them

    I have noticed some chalices like more light than others. I tend to gauge based on growth and coloration. You could also spot feed your chalices to help either way.

    I spot feed them twice a week. Is pale color too much light?

    That's the first thing I'd try yes.

    They are receiving 80 to 100 par right now with the new light and I think before they have like 130 or something.

    I grow two types of Rainbows (Gonzos Motor City Mayhem and Rainbow Crush from Cornbred) in my frag tank under Metal Halides at 500+ PAR. They do not need anywhere near this amount of light, but they grow fast and are colorful. I have kept them lower in my tanks at about 200ish PAR also under Metal Halide. I did not find that they like to be in the shadows, or anything. I do not have any areas with less light than this, but it seems like they would probably be OK.

    I have never spot fed them.

    Wow, so you have successfully put them into hight light. Did you accumulated them to this level of light?

    I just throw them in. This is high quality light - I do not believe that all light quality is the same nor a photon a photon, so take that FWIW (not wanting to start a light war). I just measured for ya and I was a little off... 455 PAR on Apogee 510 right on the meter. You can do the 1.32 conversion factor if you want... 600.6 with the math.

    Just to clarify, I would not be upset to put them in lower light... just this is all that I have in the frag tank where I mostly grow Acropora. Also, I have bounces and jawbreakers that do great in here too under about the same output.

    I’ve been wondering the same with mine. Started growing and stopped immediately. My anemone was shading it and it started STN. I moved it today after I was tired of looking at it that way. Hardy little *******. Now I have it in much higher light. Sink or swim. It is a lighter purple/pink with green polyps

    I think like said above they can survive under higher light if acclimated. I'd slowly ramp up your lights until you get to the intensity/brightness for your other corals and for what looks good in your tank.

    We have a local guy that started running his light for only 5 hours a day on his chalices and he said they really took off after he did that. No idea what par he has them at.

    I have several watermelon chalice frags in a small rack up high under around 300 par LEDs. I just put them there from the start. Their color is great and they're growing enthusiastically. I don't think chalices need low light, necessarily. What may be more important is the different between your light and the light levels and spectrum they had gotten used to before being transferred to your tank. I think this applies to most corals, and this can account for why some animals, like yumas in my tank for example, always seem to do better when obtained from one source as compared to another.
