Dying sps kill other sps

[OurCoralReef]

I recently had a big sps colony die and it wiped out a bunch of my sps encrusted frags

Im thinking its related i broke off one of the frags that was starting to die and its fine

i also made a channel in the rock encrusted part between dying sps and living tissue the living side is still alive the dying side totally bleached out



im thinking dying sps kills other sps

Or, whatever imbalance/variable is causing one SPS to die, is causing the rest.

That would not explain when a channel is made between living and dying tissue the living side survives while the dying side completely dies

Also all the levels seem ok

Im not sure what you mean. I'm just pointing out that if you keep having multiple deaths in your tank, it's likely a result of something, rather than the cause of it.

Please read the post

I agree with kevin. There's something that happened in your tank that is affecting your sps. Usually an alkalinity, or temp swing would affect sps as they are the most sensitive. Could also be a flatworm infestation. Any signs of these on the skeletons? There is a reason why the first one died and its most likely what caused the others to die as well.

No flatworms
or spikes in alk i dose manually every day
Test once a week

If it was a issue with chemistry then the whole coral would die (the second coral to start dying) the pieces that were fragged off are still living and look healthy starting to encrust again

The large colony was a wild grew a bit sometimes wild colonies just die cant survive in captivity

In the future it may be helpful to turn the blue channels down/way off to improve color rendition and picture focus..
All that blue just distorts everything..
Seems like there is also a good bit of algae there that may indicate an excessive nutrient level..

Often times the causes of coral demise go unknown.. Sorry that happened..

Sorry it was night and wanted to show what it looks like

There is no pest algea in the tank
The rocks are green and coraline no excess algea
And nitrate and phosphate is low

Please note all my other sps are doing well great growth

All you did is separate the dying part of the coral from the living coral....we do the same thing when we frag the tips of an sps when it starts dying from the base up.(rtn/stn) sometimes corals die for what seems to be no reason...that's why we frag the tips...works almost 100% of the time.

Exactly
I was saying that it cannot be a water or chemical problem targeting specific coral types


The question is does dying coral release something into the water telling other coral to expel their zoantelle

Or maybe dead sps tissue when it comes into contact with coral kills that coral
