SPS Dying

[Science/G]

Your calcium and magnesium are low. Nitrates and phosphates are also on the low side. Whether or not this is the impetus for the die off or just part of the problem is hard to say. As recommended above I also agree, a solid water change would be the best prescription here. I would also try to get those other numbers up a little bit. Sorry you're going through this.

I would definitely frag those montipora to start fresh there.

Based on 357 ca, I’d say it’s your calcium

I'd expect it to be a gradual decline if it was parameters, unless there was a swing in values. The issue i had was an overnight death, and it killed c couple of corals and part of a couple more, which is why I'm leaning towards Paly.

My actual calc level is 420 and mag 1344. Looks like I'm at the end of my reagents and this is also a misreading. THe triton results are more accurate.

The problem with ICP results is they are a week in arrears but yeah- if it has always read that low I agree to ride the trend. If your issue is bacterial, an avenue I have taken is chemiclean treatment followed by reseeding with mb7 or prodibio. Chemiclean has an unadvertised antibiotic in it which does more than just cyano control.

Imo, your parameters are fine and with testing error could be ideal, however could also be low?….but regardless I don’t believe your parameters are the issue. Also you said you directly feed corals which, imo, is very good. I think your plan of a large WC is you best action. Might want to check all inputs and equipment, example rust, for contamination.

With what you've described and in correlation with the time frame of decay my guess would be a bad piece of equipment. Most bacterial issues will be a more drawn out event claiming the most susceptible first only to move on to the next and possibly not effecting anything at all. I didn't watch the video but I don't think there's anything Julian is going to say that would make me a believer that palytoxins are deadly to other inhabitants. My bet is that you have metal in your system.

If those tests are accurate nothing is out of wack. Calcium is fine as is Mag. Could be higher but aren’t so low they will cause this. That’s not how it works.

Likely bacterial. When was the last time you added something?

Interesting, a flipper not in the best condition has been stuck to a frag rack right next to these corals. I removed it yesterday, but

Will investigate, thx
