Brown Jelly Disease and Crocea Clam??

[Coraline2020]

I hope someone can help me...I have a 6mos old Aquapod 24 with 70W HQI. I purchased a Crocea Clam 2 months ago, and has been doing fine until now. I recently had an outbreak of Brown Jelly that took the lives of my Candy Cane and Open Brain coral. Now the Clam is showing slight signs of pinched mantle (one side near rear of clam is curling inward). Could there be a correlation between the two incidents???

Here are the Tank Params:
Spec Grav: 1.025
Temp: 78-80
Nitrites & ammonia both 0
Nitrates ~10
alk 10
Calcium 460
pH 8.3

Inhabs: Ocellaris Clown, Yellow Watchman, Longnose Hawk, Turbo Snail, Cleaner shrimp, Spotted Linckia, Kenya tree frag, small colony clove polyps, med green star polyp colony.

The clam is approx. 6 inches from lighting on rockwork and has long since attached there. Any help you folks can give would be greatly appreciated.

I'm sorry, that I don't have pics to post, but could tomorrow if need be.

[welcome]

that will help a lot if you could post pics.

what exactly do you mean "brown jelly"? what did you do to get rid of it?

tell us more about your filtration, additives and chemicals you use

Thanks for the reply mbbuna....False alarm (I think, HOPE)...clam was doing fine last night when I got home from work and again this am...so no pics to follow

I think "brown jelly" is correct term...it is a protozoan that causes LPS tissue to deteriorate at an alarming rate...tissue literally turns to brown jelly-like substance within hours/day...tried Seachem Iodine Coral Dip on CandyCane without success...finally removed both corals from tank to prevent further spread...these were the only two LPS corals in the tank (my first, and probably last)

Filteration is 2" lsb, and 20+ lbs lr, sponge filter in overflow chamber...I run carbon and purigen on regular basis...tried Fission Nano Skimmer (JUNK!!!!!!)...so have no protein skimmer...still all water params OK except nitrates which are being lowered with more carefull feeding and regular water changes (at least 20% weekly)

Thanks again for your quick reply...will post back again if more problems arise...

BTW, I am considering changing current 70W HQI (14,000K) for 150W (14,000K) for the acquisition of Bird's Nest coral in the near future (after sure no other problems with current set up)...do you think this would benefit, or be overkill?....tank 20" deep with lights on legs 2" above water...plan on Bird's Nest in upper 1/3 of tank(am saving his place on rockwork).

It may get hot

i think the 150w would help.

back to the brown jelly, are you sure it wasnt cyanobacteria?

 

[Coraline2020]

Definately NOT cyano...coral flesh literally turning to brown goo and peeling off in the current....right down to the white skeleton in a matter of hours!!!!!!!!!

Never seen anything like it before...did some internet research and "Brown Jelly" disease is best description and pics I could find, (search www.wetwebmedia.com for brown jelly)...

Anyway, thanks to everyone for the help...I'm just thankful I only lost the two corals....

It is bacterial I believe.
