is this brown jelly disease?

my only problem is that the area has increased in size and it does seem to be taking healthy tissue w/it from what you guys have replied i think maybe it isnt brown jelly but there is something not right,what else could be doing this and what steps should i take it is a nice piece,and dont want more damage any help is greatly appreciated.

 

Parameters please, swings in alk can cause issues with lps and tissue regression.

Lighting please, the color may be off in the images. The corals look a tad light and or bleached in images.

Are you feeding the coral?

 

I realy can't see anywhere that the tissue is receeding. It looks completely normal. Is it possible the tissue is slightly deflated and thus making the spot look larger? There is no new skeleton showing....

 

spec grav 1.025-26 cal 430ish mag1200 alk around6.9 lighting is 2/250 hqi mh bulbs 2 months old feed oyster eggs and some phyto rest of tank is fine acros ,clams blastos acons no other problems i will try to put up some other pics , i know it dont look to bad and the recession has been slow but i see it. i know the main part that was damaged is old but thats why i wasnt worried when i bought it i figured it was old and had healed and all was good

 

I would bring up the mag and alk then and see if that makes a difference, and depending on the depth of the coral, that is a lot of light for an lps.

 

brown jelly

the coral is on the bottom somewhat out of direct light,the reason i thought it was brown jelly was it looks brownish on the edge where its seems to be receedingi tryed a couple more pics but it is not a lg area,thanks for all the input.

 

Beautiful tank.

I would be hesitant to make any changes since the sps are growing so well for you. I wonder if those of value of mag and alk are correct.

Are you running any GFO/ bio-pellets/ or dosing carbon?

Again beautiful tank, stunning clam.

 

Do we know for sure what coral we are dealing with here? It looks a lot like Merulina ampliata to me...in which case it's not an LPS...if so it is a fairly high light coral and also likes a fair bit of flow.

 

i was dosing vodka at 1 point but stopped found better way of dealing w/hair algae i dont use anything else weekly water changes crank the skimmer i do put a 100 micron pad in sump but other than that nothing.parameters might not be true i dont always test when somethings wrong i can tell by inhabitants,might not be the best way but it has worked good for me so far thanks for compliment that is 1 of 3 maximas i have love them have had them for many years got them when they were about 1 inch

 

lighting not a problem flow is also not a problem plenty of both
