what wrong with this brain? (picture of it dead now)

Agreed. Should have mentioned Radion in the first place, lol. My Wellso doesn't like to be directly under the led's. Its probably 6" to the side.

Frogspawn can take a lot of light, but they have to be SLOWLY worked up to it.

 

Ok, if i need to i can reduce it down to 55-65% if i see its not accepting the light. That dfrogspawn i had was fine for aboyt two months directly uner 100% radion

 

But its a cumulative thing. They can take higher amounts of light, as long as they're healthy. Your corals will die quicker with too much light rather than too little.

 

good morning. i very carefully compared yesterdays picture of the brain, to what it looks like this morning, and there is no change what so ever. I'm beginning to think that those two spots that have tissue damage are from me, when i was positioning it into my aquarium. Which sucks, but on the other hand, id be glad to know it was me and not some mysterious random tissue killer. Could that be the cause?

 

I am with the others, tissue recession from the Radion fixture.

Although I have never had that fixture nor LED's, I know from experience that Trachyphyllia and closely related LPS do not need as much light as we think they might. Low in the tank on the sand bed not under direct lighting initially and feed it.

 

Will do corailline, and thank you

 

For example, my Wellso is 29" below the light, and 8" off to the side, using 120 watt LED's.

 

turned for the worse. the tissue in the effected area has peeled all the way back to the mouth of the coral. so far it hasnt spread, just got sever in that one area. I think that if i keep moving it, then ill do more harm than good.

 

Yeah, they are hard to move. You have to get your hand all the way on the bottom, not pick it up by the sides where the flesh is. I had mine recede nearly half way, and got it to grow back.

 

Any improvement yet?
