Coral Problem?

I wouldn't do that. If he/she accidentally brushes the healthy tissue, it could very well start a RTN event. If I was going to do anything, I'd snip the dead ends off.

 

Dont gentley remove the algae with a soft toothbrush! Cut the ends off instead ha ha

 

should be ok, but i do not think it is a birdsnest, i could be wrong and i do not have much SPS but all of the birdsnest i have seen look different than that.

 

1st question is What type lighting do you have and what are the Ca and DKH and mag levels of the water running at ?

2.nd have you ever kept acroporas before ? or any experience at all with SPS coals ?

If you get it happy by meeting its light and water quality requirements and get it to start growing it will regrow over the dead spots . I would not brush it with anything .

 

For lighting I have 2 -250w MH with 4-55w PC's. I have about 9 or 10 others SPS corals in the tank doing pretty well, including some acros.

Ca is 440
Mg is 1300
Ph is 8.23
Temp is 79.6
Ammonia, Nitrite, Nitrate=0
Salinity is 1.024
Kh is 14 - I cant seem to lower this for some reason! Unless I have a bad test kit.

 

lower your alk and cut the bad parts off and refrag the rest
