Bleaching question

[tufacody]

I have a 180 with various softy corals. They tank is about 5 months established. It is lit by a new 72" Solaris. Water params are near perfect.

With one exception, the corals have all done very well. The exception is a donut or meat coral. This is supposed to be an extremely hardy coral, and the LFS had it for a long time before I purchased it.

Admittedly, my tank has too much flow for some of the lower flow critters. I think I've done my best to curb that now. But the donut developed a small tear. I fixed it up with superglue, and it healed well. However, shortly thereafter I noticed that some of the feeding tentacles had turned from brown to white. As time passed, even more turned white. I tried various placements in the tank to no avail. Finally, I moved it to my fuge which is much lower flow and PC lighting. That hasn't helped either, and I'm sure its on its way out. Now the entire "center" area surrounding the mouth has turned whitish as well.

My concern now is that I think the very tips of my galaxia are starting to pale up.

So, my question is this: based on what I have said, does this appear to be a problem of too much light or too little light, and can these sysmptoms be caused by too much flow? This is my first Solaris light so it is hard to know what to expect. I need to make a decision on where to place the galaxia so it doesn't suffer the same fate. However, it is on the bottom of the tank now. My only options would be to move it in a cave, or put it higher up.

thanks

I dunno if patching a tear with superglue is a good idea cuz superglue can burn the tissue of corals if not placed immediately in the water to cool it. It's usually used to glue rock to rock and normally wont stick well on actual tissue. If you glue a loose shroom to a rock almost always it lets loose within 2 days.

As for the galaxia it's hard to say. Solaris lights are so new (lucky you those are on my wishlist for when I win the lottery lol).
I would try moving it again maybe under a cave somewhat but I'd keep it towards the bottom.

Maybe someone more familiar can help you.

I would leave the Scolyemia in an area of lower light, and lower flow, rather than constantly moving it around. I don't know how much flow can contribute to a coral bleaching - excessive amounts of flow however, can damage a coral by causing tears in the flesh, or not allowing the polyp to open up. I would imagine the bleaching is being caused by either the tanks water parameters, or the lighting being too intense. If you have water problems, rectify them. As for the lighting, I would try and move the Galaxea away from the light for a while and see how it does. Try feeding the Scoly some mysis shrimp, or any other small meaty foods (because of the loss of zooxanthellae, it can't rely on photosynthesis for it's metabolic needs like it could at full health). If it eats, then great - it should be fine; just be sure keep up the feedings to help its recovery along as much as possible. HTH!
