Help
I have a couple of softies left in my now mainly SPS tank, I have been trying to shift them for a while as they are growing like crazy and take up a lot of space.
A few weeks back a few branches bleached on my Acro Nana, my fav purple Stylo also bleached out near the base and on a few braches. My Monti Cap' looked stressed a few days ago and last night my Hystrix started to bleach.
All four are in the same end of the tank, near the softies, so I am now wondering if the softies are secreting something which is stressing the SPS next it them?
Cheers

i never know what to think about this one, as ive seen tanks online and in books that have a lot of each coral and there dosnt seem to be a problem.
i have read that the softies you are giving away are one of the most toxic softies people keep, so it could be them i guess

Googled the following...
"Leather corals release a toxin in the water which has an damaging effect to less hardy hard corals. These toxins do not usually kill hard corals but does have a negative effect on the growth rate of effected corals. This effect can be lessened by the use of chemical filtration. You can keep leather corals with hard corals even without chemical filtration but you should be aware of the effects this have on your hard corals."
"The Lobophytum genus is known to release toxins that could damage and possibly kill near by corals. Sps corals are especially sensitive to these toxins. I have never had this happen but I still take precautions to prevent this. "
My softies have been growing quickly and are now pretty large so I am assuming they are starting to release enough toxin to affect the SPS nearby. I have found takers for the soft corals so it will be interesting to see it the problem goes away after they are removed.
EDIT:
While using a baster to wash detritus off my orange Monti’ I realised the flow of water is passing under the Monti' and the powerhead I have aimed to keep it clear of detritus was creating a flow pattern over it and through the other 3 affected SPS. Maybe that would explain it?

Look at Andreas tank second down on the left on this link. The tank is skimmer less and sump less and then make up your mind if leathers don't get on with sps. But you might have a different stronger one??????

Softies secret a toxin, how much that affects SPS in a tank and under what conditions it will cause problems I don't know.
I have had these soft corals since I started to keep SPS and have had few issues, now however something is stressing a few SPS in one area of the tank. Toxins from the two large finger corals could well be doing this, combined with the flow and the fact that both finger corals are next to each other. The finger corals have also been stressing (retracting) a lot recently due to the Goby dropping sand on them, maybe this has been causing them to release more toxin than before.
I have no doubt that if the soft corals were spread out and the flow etc was different I might not be experiencing problems.
