Is this RTN? Will is spread to other frags?

[Biff0rz]

This frag was given to me for free, it's a green slimer but it's got a green birdsnest attached on the same plug (came like that). It looks like the slimer is starting to rtn. The birdsnest is actually recovering and coloring up, both came from undergrowth. Should I superglue the flesh or just tear it off and chuck it? I'm new to sps, so not sure if this will spread to other frags. Other frags from the same tank/day are not having issues.

Some will chime in and say to post up your tank age, parameters, and pictures to assist. I agree, to a degree. Balance and maturity of the system will likely determine whether I would personally chuck it or not. Took this coral from dead to one of my favorites

This is a coral qt - dt is new and doesn't have any sps in it yet. I have another slimer which is doing great. Coral qt has a few frags, I'll attach a pic.

QT age is 3mo

Params, taken last night
Salinity 35.5ppm
Phos 0.2 (hi713 / ppm)
Alk 12
Trates 0
Trites 0
Ammonia 0

That tank is way too clean.

 

[Perry]

What scares me is no no3, but 12 dkh. I personally would lower kh, or raise no3.

 

[ReefPig]

Yes
and maybe it'll spread, maybe not, I've had it both ways.

Edit:
The tank looks brand new, not mature at all, SPS will almost never survive in new tanks, particularly if your params are out, which they are by the look of things.

 

[Biff0rz]

What scares me is no no3, but 12 dkh. I personally would lower kh, or raise no3.

So the dt has one fish, and I have awc to the dt and another awc which transfers from dt to qt. I've been feeding the fish a bit (2-3x/day) and no change in no3. I've also been ghost feeding the coral qt with some mysis scraps. Was going to get some algea pucks for the cuc.

What's the best way to lower dkh?

 

[Biff0rz]

Also, I'm going to test alk and trates again today.

Don't buffer, or choose a salt that mixes at your desired parameters. Then do 10-15% water changes, and SLOWLY lower

I'm using IO, the mixed dkh of that is pretty low, isn't it? I haven't been buffering or dos'ing anything. There is the possibility I tested wrong. Using a red sea kit. Hanna reagent is on its way..

 

[vetteguy53081]

All is high and likely a cause to this.
Moderate lighting at minimum and good water flow

temp 76-79
Salinity 1.025
Ph. 8.1—8.3
Mag 1300
All. 8-9
Ca. 450

Not sure, I have found the following salts great for sps tanks with lower nutrients. Red Sea Blue bucket, Tropic Marin Pro, Aquaforest Reef, and Brightwell, I say this because they all mix between 7 & 8.5dkh at 34ppt or 1.025 SG. I remember IO being a good stable salt, but a bit higher in kh, but has been years since I used. If you have the $, Tropic Marin Pro is my favorite choice, but I use RS blue bucket and have zero complaints

 

[Biff0rz]

Is a 6 hour photo period too long? 4x T5. It's a small 30" Coral life fixture

 

[Perry]

Not sure of that fixture, it's no ati lol, that is the gold standard of t5. If you can access a par meter, that would help. And 10 hours of t5 is just fine

Aren't they going to attack each other being that close together?

I actually have a bucket of tropic Marin pro sitting here, haven't cracked it open yet. Yes I have the money to use it vs IO. I'll try it out. I have about 15g of io mixed and in the storage container still.

Heh, yea, it's just for the QT. 10 hours? Hmm. I had it at 9, so that probably is fine.

 

[Biff0rz]

Ok tested again.
Dkh is 10.5
No3 is 0

Should I ghost feed more to add some no3?

 

[John08007]

What is your biological filter?

 

[Biff0rz]

On the dt I have live rock (cured over 6mo and came from an established tank) along with a roller filter. On the QT I have small amounts of lr in the tank (same from dt) along with matrix in the Hob. Also added some chaeoto a few weeks ago so I can get it in the dt sump.
