smarsh Posted June 25, 2008 Posted June 25, 2008 I had got a green acro about 2 months ago. I quickly learned that the PC lights in my tank were not enough when it turned olive green/brown. I got new T5s about 3 weeks ago and it has been turning neon green with full polyp extension. Today I noticed a white spot on the side of it. Looks like there is no tissue there. It got a little bigger throughout the day. The coral looks fine but im not sure if this white area is going to spread more. I have gone through so much trying to save this acro and it has been doing better every day. Tank is testing fine. Should I cut it bove the white spot and attach it to a new plug? Any suggestions would be appreciated!
Oceanic 30g Posted June 25, 2008 Posted June 25, 2008 Where is it placed in the tank? Can you provide a FTS and a shot of the spot? White spots usually indicate bleaching which is the functional equivalent of a dead spot. Pics would help though.
abe Posted June 26, 2008 Posted June 26, 2008 spreading? could it possibly be RTN? or it could be bleaching, but i doubt it, bleaching is much slower. it probably has nothing to do with lighting, most likely, it is tank parameters.
Reef Goddess Posted June 26, 2008 Posted June 26, 2008 Sounds like rtn, hopefully not. Maybe try dipping it if it continues to see if that will stop it. Maybe the change was too sudden for it from crappy lights to better lights. Sps are funny sometimes. I had two colonies of identical purple valida growing right beside each other and one day one of them started rtning for no apparent reason. It was gone by the next day. The other valida and all my other sps are doing great. ???
gulfsurfer101 Posted June 27, 2008 Posted June 27, 2008 I've had some turn white at the base and within two days it was completely lifless. It had to do with excessive nutreints in the water. SPS need an establihed tank, good skimmer, and pristine water condtions to thrive. I would do a twenty percent water change and hope it hangs on.
smarsh Posted June 27, 2008 Author Posted June 27, 2008 The spot got only a little larger today. The acro opens so nice now, it hasnt looked this good since I got it. It is really neon green today. Reef Goddess, What kind of dip are you speaking of? Lugols? Thanks for all your help everyone!
Detritus07 Posted June 27, 2008 Posted June 27, 2008 I don't think you're supposed to used lugols on sps. I was told to use tech-d
Reef Goddess Posted June 27, 2008 Posted June 27, 2008 An iodine dip or Tropic Marin Procoral Cure. And maybe check for flatworms.
