Need help, coral dying--picts inside
Hey everyone,
I bought these two guys about a month ago. They were doing great a the LFS, but have been fading in my tank. Any thoughts on what I could be doing wrong? Parameters are below. ca-425 kh-8 ph-8.3 no3-0 p04-0 temp-80 salinity-1.026 lighting is T5 HO 8x54watts coral is about 18-22" from lighting Thanks! |

No pics, but my guess is either they are bleaching because you didn't acclimate them to your lights/placement, or your T5HOs aren't providing enough light at 22" away. Do your T5s have individual reflectors?

My first guess was the light. Either not enough or too much to have not been acclimated.

thanks |

feed more, that coral looks like it would prefer 5-10ppm nitrate.

It looks like bleaching. I don't think it's from too intense light, but perhaps there is some other parameter that is off. I've seen ones look worse than those and rebound in a few weeks, but something is off with the tank.
What kind of Maintenance routine are you on? Any Kalk spills, temp spikes, or dosing you've been doing?

my maintenance routine is pretty simple. i check parameters once a week and do monthly water changes. i dose Kents CA and KH accordingly.
it's weird because my other corals look great. i'm super confused about this one. |

How old are your bulbs? Age causes color shifts which corals do NOT appreciate.
What other livestock do you have in your tank? |

thanks for all the feedback. bulbs are 2 months old--so i doubt that's it.

i would also agree that they will bounce back. did you change the light? or are these new frags. mine did the same thing when i got new lights and whenever i added a new frag that was from a tank with less intense lighting than my metal halides. they just went through light shock, and i cut back the photoperiod and put the frags in the bottom of the tank for a month or so and then moved them gradually higher up in the tank.
