View Full Version : New Hammer Coral Spewing Brown... Jelly, Zoo, Trouble?

Hi!

I have a 6 month old 14 gallon nano (Fluval Evo) that has been doing great. We have 2 clown, 1 blue damsel, 1 Rainford Goby, basic clean up crew. For corals, have zoanthids, a pulsing zenia (growing and pulsing nicely), 2 headed torch coral, Long Polyp Leather, 2 Duncans, Bubble Coral, Green Polyp and Metallic Green Hammer Coral (the coral in question)

The metallic green Hammer was added to the tank exactly two weeks ago with a couple frags of the green polyps. It was doing totally fine, opening every day, closing a bit a night. Unfortunately I had to leave town last Friday for a family emergency out of state, and left the tank in care of very capable girlfriend - she can handle the basic feeding and watching the tank, she doesn't overfeed.

I tested parameters right before I left and they were great:

Salinity 1.025
Temp 77.9
Ph: 8.1
Nitrates 0
Phosphate 0.09
Calcium 400
Alk 8 dkh

We do a weekly 10% water change.

I have a couple of Arlo cameras on the tank so I can spy on it when I'm travelling just to make sure everything is ok. I noticed over the weekend and progressing through today that the hammer was not opening and is expelling some brown gunk. I've tried to read up on the forums about this and see conflicting reports (based on different people's photos) that things like this could be brown jelly disease or the coral is expelling it's Zooxanthellae.

I wanted to post my actual photos for real opinions on what's happening with mine, if anyone can help. Unfortunately I'm not home and won't be for 3 or 4 more days. I can try to direct my girlfriend what to do if anyone has ideas. Hoping for input that it's going to last until i get home and can test water again.

EVERYTHING else in the tank is perfectly fine and doing great.

Also of note (and wondering if this could be it) - one day before adding this coral, we upgraded the tank lighting from the stock Fluval lid lighting (primitive on/off white or blue only tank light) to the AI Prime HD+ with a nice light programming setting and schedule recommended by many others. I put it on a 3 week acclimation schedule to ramp up the lights from 50% of setting to 100% of setting over the 3 weeks.

I'm curious since the hammer looked great for about 5 days then slowly started to do this (looking like these photos today) - do we think the AI Prime (only at 50% and acclimating is not acclimating slow enough and the coral started to react to too much light? Again, everyone else is fine. I think it's interesting that the coral looks best on the ends (where it's under the shade of the live rock) and worse in the middle, where it's under direct light.

If this is a too bright of light issue, i can lower and extend the acclimation schedule.

Based on these photos though, do people agree with this assesssment? Or am I in more serious trouble? Will it recover? I'm hopeful since I do still see a lot of green throughout, it's just expelling this brown stuff but the polyps still seem nice and green even though they are withdrawn significantly.

Thanks for any advice!

Looks like its dying, flesh melting away. Most likely it wont recover.
