Why is my Chalice Bleaching?

[fab1971]

Remember there can be a variety of things that can be going wrong, you just have to double check your numbers (bring a sample to a lfs for testing), watch out for any faulty equipment, double check for salinity errors and keep on the lookout for predators or fish picking. That way you can start eliminating everything and get closer to the reason why some of your corals aren't doing so well. If all of those check out, along with your numbers, then I'd look into maybe dipping. Could be that there is some bacteria present but the simpler sollution would be one of the others. Might also be the type of corals that are dying. Where did you get them? either way, good luck figuring it out.

How was the alkalinity boosted up?

What are you feeding them? With 24" bulbs I'm guessing a 20g tank? What's your fish list. Bleaching also occurs when there's not enough nutrients. Don't forget corals run off algae. Algae needs phos/nit for photosynthesis. So no matter what your params and light are they will bleach and die if your waters to clean.
