Favia with white spots

[badger126]

Wondering if anyone can help me out.....I bought a favia 3 or 4 weeks ago and it has developed some whitish areas. It is a green favia with brown ridges and the white is developing in the bottom parts of 2 of the green "eyes"(I don't know correct coral terminology). Water parameters are spot on - no nitrates, calcium and alkalinity in range, temp is 86, etc. I didn't think it was a bleaching issue since it's so localized, in only 2 of the 9-11 polyps. The coral has seen good growth, all the polyps that were severed when fragging have healed or almost healed, and the entire favia has grown 1/4-1/2 an inch in every direction since I glued it to the rock. Any ideas on what the white spots could be?

Temp is pretty high. If your running at 86 constantly you need to get that temp down.

Really? I was under the impression that ideal reef temp was anywhere between 72-78 degrees. What's ideal for temp then? I'll change it

 

[Chichas01]

you said your temp was 86. 86 is greater that 72-78

oh crap I did say that huh? I meant 76 sorry. have any other ideas?

About ur Mg? Ca? Alk?

I've noticed Favias and Acans do not like Alk. When I tried to get my alk up for the SPS, my acans/favias suffered severely.

I keep my Alk ~9dKh and haven't noticed any problems with my acans. I don't have any favias, so I can't say anything about them...
