Donut coral losing colour.

[Ali-F]

Hi all,

I have three nice donut corals that used to look very nice and doing so good. I never attempt direct feeding before as they were located in a spot where the pallets I feed the fish falls directly into them.

Then I had to increase the intensity of my light and then started to see them bleaching. So I had to move them to a shaded area hoping that they will recover. But they did not.

I move them back to their original place because I think now they will not recover their color because like of nutrition.

So I am asking which one is the reason? Strong light or lack of nutrition?

What do you advice?

what's your nutrients level at? and donut coral don't need lots of light

They tend to like lower light and flow. Sounds like you are working on that. Also feedings after lights out usually. I would start with mysis first and move up to clam similar. They are pretty. I hope they pull through okay.
I had an Acanthephyllia that was big and beautiful then another coral fell on it overnight and destroyed half of it. I kept that half for years after, but in all my tank moves, it finally gave up the ghost. More from my lack of focus, so work at it and they will come back.

No3 between 5ppm and 10ppm and po4 is 0.09ppm. I reduced the intensity for my light to 75% at the peak time ( I am using T5 8x80w).

Thanks for your encouraging words.

I started spot feeding 3 days ago. I am mixing mysis and reefroids with water tank and feed them.

I am planning to do this on a daily basis for a week or two. Then if I see a good sign, I'll reduce the amount to every other day until I do it twice a week.


And sorry for your lose. I hate when such incidents happens.

Sounds like a good plan. If you can cover them somewhat to keep food near them, that is good. Just do not get them overloaded. They look pretty good. Should recover with care.

I turn off the wave makers during the feeding session so the currents won't blow the food away. But the fish race to eat the mysis too. I was worried at first but I think this will make sure there is no left over in the tank.

I might delay the feeding time until 10min before the lights turn off.

So it least both fish and the corals will have their share.
