Frogspawn - not opening, Help

[reefkid58]

I purchased a frogspawn coral this past friday and it has not yet fully opened up, and this morning had the brownish stuff you can see in the picture on its skeleton.
I have a 75g tank with close to 100lbs of liverock that has been setup for close to 2 years. My lighting consists of 4 power compacts and a strip light totalling 300watts. (the frogspawn is about 5 inches from the surface) my test readings are as follows:

ph 8.2 (a.m.)
Nitrate 0.0 (as my API test kit says anyway)
Nitrite 0
Ammonia 0
dKH 12.6
Ca 510
I also just began adding magnesium but my test kit is on the way

I routinely add the following kent products;
Coral Accel, Essential Elements, Coral Vite, Strontium & Molybdenum, PhytoMax, ZooMax, ChromaMax, and just started adding Lugol's Solution too.

My inverts include; a fancy toadstool, green star polyps, an elegance coral, feather dusters, waving hand coral, a trumpet coral frag, about a dozen frags of zooanthus, an Atl. carpet anemone, and several rock anemones, black longspine urchin, green brittle star, and a cleaner shrimp.

My fish include; yellow watchmen goby, 3 green chromis, yellowtail damsel, black percula clown, and a powder brown tang.

Any insight would be greatly appreciated as I am leaving tomorrow afternoon and wont be returning untill the end of the week, and dont want to kill this animal.

mine was pretty closed up for a day or 2 when i first got mine. After that it seemed to open up when the lights are on and then close once lights go out. other than it just needs more time to acclimate i don't know what to suggest since i am new to this as well.

Any idea what the brown stuff forming on the skeleton might be? Also, how many watts per gallon do you have on your tank?

looks like brown jelly disease to me... hopefully i'm wrong. but if it is, the prognosis for recovery is not good. do a search for "brown jelly".

if you can take the piece out, try dipping it in coral revive and/or lugols which may kill off some of the bacteria causing the brown jelly and promote healing. but don't quote me on that. if you can, gently turkey baster off as much of the brown stuff as you can. if it looks pervasive, try to frag off a healthy section and start over with that.

finally, someone is bound to say it so it may as well be me: don't dose for it if you don't test for it. you're dosing Mg, but you don't know how much is needed. same w/ the lugols. iodine/iodide is tricky and too much can be problematic.

good luck!

When mine had the brownish they were dead within a day or two. Let me know if yours survive.

It dosent look good, looks like brown jelly disease to me to. Hard to tell maybe you can save a few heads and dip them.
