What happend, everything white

[hkgar]

Two nights ago my leds (3 AI Sol blue) stayed on, because of a unplugged wire, until I awoke about 1 am and noticed the lights. I got everything reprogrammed yesterday morning and then left for several hours. When I came home all SPS had turned white.




I had the led's set at 95 white, 85 blue and 80 royal blue. I also use two t5's, a 10000k and an Actinic.

180 gallon tank Nitrate 0, phosphate 0, ALK 7.9, CA 425.

I am afraid it might be RTN but am hoping that it is just bleaching from too much light.

I have turned down the led's to 55, 45 and 4o

Any ideas and help would be appreciated.

Thanks

They are dead. I doubt it was your lights staying on that killed them.

How can you tell they are dead from those pics?

It doesn't look like there is any tissue left at all, just looks like the skeletons.

If they are dead, what would have killed them in less than a day.

I dip all new corals in Seachem Coral dip for 10 minutes to, hopefully, kill any incoming disease or parasites

Is my tank safe for new corals? I have 5 showing up tomorrow from LA.

They are bare skeletons. There is no flesh left. They are dead. To be sure smell them. If they smell like coral then they may still be alive, doubt it, but possible. No smell, then they are dead for sure.
I would bet you money that they are dead from looking a them though. I have seen a lot of corals, both dead and alive. Based on the pics, I am pretty sure about these guys. They are dead.

Most things that would kill a coral will do so in less than a day. There are plenty of people on this forum that will be glad to shoot in the dark and tell you a million of them. Unfortunately I don't know anything about your tank, and wouldn't even begin to assume that I could troubleshoot it with out knowing a lot about your system and set up.

As far as what killed your corals, I have no idea. I don't dip but I do know dip kills a lot and that would be my first call.

But from the images linked, the tank looks pretty new to me. That doesn't mean it cant be ready for sps but in this instance I would say, it probably isn't.

It probably isn't ready for the corals you are going to receive tomorrow either.

New is a relative term, but this tank was set up in early January.

How old should a tank be before adding SPS?

How do you know when a tank is ready for SPS?

 

[tmantaylor18]

any other coral or fish in the tank? are they ok if so?

 

[hkgar]

Fish = Yellow Tang, Spotted Breast Angel, Flame Angel
Several LPS and a few Plates

Every thing, except the SPS is just fine. About eight SPS - gone

Man that's terrible I would err on the safe side and not add those new peices wait a while and hopefully whatever killed them will starve out if you don't have another tank or a friend to coral-sit then I would check with ur fav LFS and see if they will watch my place here in Melbourne will do that and if you have a good relationship with anybody at ur LFS then they should have no problem coral-sitting. I'm so sorry for the loss but that's the thing with this hobby were trying to recreate what nature has perfected and we are human.

That's crazy. I wouldn't think that a little extra light for 1 night would have done that. I have corals in my fuge with light on 24-7 and they're fine. Haven't tried that with an SPS though.

Anyway, like one person already mentioned it is impossible for an outsider with virtually no info to diagnose this. It was a rapid stress of some kind. Did any equipment fail? Heater, dosing pump, stary voltage? Who knows. I'm curious to know what you determine to be the cause.

Depending on your system and methods 6 months may be plenty of time to establish an SPS tank.

I would expect the sps to do well when conditions are such that coraline will grow. However I have set tanks up ad added sps immediately when moving from one established tank to another so the "age" of the actual tank isn't that relevant. Its the age of the system that matters. The system can be moved from tank to tank or established quickly. I was basing my comment regarding the tank being "ready" for SPS by the cleanliness of the rocks, your losses, and your comments. Just based on the small portion included in your tank, it doesn't look ready for SPS to me.

When every thing in the tank is growing like crazy, then your tank is ready for SPS. That's my opinion, but i don't run systems the same as most people. However, here is an image of part of my system, so it does work.

Check out some of my threads if your interested in finding out what i do different.

Nice looking tank! What are some different things you do? Any recommended posts? I looked at your posts as suggested but it's hard to find stuff. Thanks!
