I have had a few corals bleach out on me recently. A blue stag completely went white. Along with a green Millie and a rainbow monti I had. Then it started happening to my tricolor and my bonsai. My calcium is 475 alkalinity is 3.76 meq. I was thinking maybe magnesium was low so I dosed a couple ml over 2 days. And it's seems like it's getting worse. Then I thought I just had to much light over them because I don't have any fish in my 74g. So I've fed them today and yesterday. Corals all eat healthy. Any ideas? I know I need to test phosphates nitrates and magnesium to get a better understanding but anything like this ever happen to one of you?
 
Bleaching

Bleaching

Depending where you live it might be chlorimine? Do you have ro/di?. Water changes might make it worse. Hope it gets better. Any visual bugs? pH? Do you run carbon? What are the other water parameter?
 
I get my water from the LFS. Don't run carbon. Don't know what my ph is. And no visual bugs or pests. I searched hard
 
Hey Colton I have test kits for phosphate, mag, potassium, nitrate and pretty much anything else you want to test for. Bring over some samples and test away lol.
 
Alot of folks will argue :), but Alk too high for me. I like 7 dKh but probably not your problem anyway. Make sure phosphate as low as you can get, Nitrates should be near to nothing and Calcium400-420 mag 1300 ish. I think your going to find either lighting (what are you using) or if your nutrients are so low maybe need to feed but... usually low nutrients are not a problem with most reef tanks. If things were "normal" and this just started happening, did you change something? Are you wet or dry skimming?
 
Skimming normal I don't add water in the collection cup. And I have radions customized that are more then a foot over the water level.
 
Been running radions the whole time since tank has been up. And I believe they are on 75 percent. But if that's too high or low why did the corals do great for a few months then outta nowhere they start going one by one.
 
Ive had a very similar issue, lost quite a few colonies, once the tissue necrosis starts, it wont stop on its own, only thing to do is frag above. Im not sure what caused it, most my values were stable, did cut back on reds in my radions, put mag on doser to keep it more stable, unplugged grounding probe(HIGHLY DEBATED ISSUE)and stopped dosing seachem reef plus, upgraded to larger skimmer as my ph was a little low Everything, knock on wood, seems to be recovering now, so not sure what exactly caused it. Im also bb, and maybe a little to clean, so im feeding more, did you by chance change out your lenses on your radions, i was running tir w gen 2 radions, then changed them to the wide angle ones. Good luck, let us know if you find anything.
 
That's why I call these "Grief Tanks" not Reef Tanks!

As Bill did, make small incremental changes and watch for positive results would be my only suggesting at this point. These things will drive you nuts!
