What's going on with my coral?

[Be102]

I originally suspected that my Duncan ended up messing up the red coral and the blue one, (half blue half white now) by falling over due to the current. Today I noticed my other coral (no clue the type, identification would be cool too) is starting to turn white on the edge closest to the blue one.. any ideas? My other corals seem fine.

looks like they are bleaching. Wondering if they are getting too much light. How long have you had them?

Few weeks.. but that is definitely a possibility I just changed my lights... I guess I can just cut back on the light period?

move the bleached corals to the bottom of the tank

Do different spectrums of light affect the corals differently? Similar to how white light is good for algae growth? For moving it to the bottom, can I lower my whole frag rack? Feel like he's a little too little and will get knocked out of the rock work.

Looks like some of your corals are happy there and others are not. I would keep the rack there with the happy looking corals and move the bleached corals to the bottom. Different corals have different needs in light intensity and flow. As far as spectrums go most people choose what is visually better for them. Some like blue lighting and others want natural sun look. Most reef light systems offer the necessary spectrum. Hope this helps

Thanks for all your help!

Anytime. Just pay attention to the corals response to their location. They will tell you when they are happy with polyp extension. Flow and light intensity and water chemistry are the biggest factors for your corals health
