What type of coral has the STN?

 

[fishflorist]

I will keep an eye on it.

Still not able to stop STN on my 1 coral. Very frustrating.

what is STN ?

 

[mos90]

im not sure exactly what it is. it was a free coral sent to me with an acropora crab.

it looks like a german blue monti a little bit. could be some type of birdsnet also. ill snap a picture tonight.


i will give u the short version. i was in the process on light acclimating all my corals to my new leds(ai blue's). apparently i went a little too high too fast and noticed bleaching on the so called "mystery coral" my closed brain and my toadstool. all the other corals are either up top or high light corals and were not effected.

so i lower the lights from 80/80/80 back to 50/50/50. all the bleaching has repaired itself, but thats when the stn started. im thinking its stressed from the bleaching triggered it or possibly a combo of stress and when i treated with chemiclean(about the same time i lowered the lighting).

here is my lighting ramp now.
8am 0/3/3 30min ramp
1pm 55/55/55 180min ramp
6pm 0/10/10 120min ramp
9pm 0/0/3 60 min ramp
12pm lights out

what is STN ?

Slow Tissue Necrosis. Tissue dies slowly and is lost.

RTN is rapid tissue necrosis and very fast.

[mos90]

found a picture.

 

[mos90]

any ideas what coral that is? it seems rather difficult to keep if it is a montipora.

 

[Randy Holmes-Farley]

I'm not sure, nor do I have a good answer the the STN.

Do you use GAC? That may help if there are any toxins in the water, but I wouldn't count on that being it.

 

[mos90]

ive been using 1/2 cup of brs rox carbon. i change it out every 2 weeks.

i never realized cyano could realese toxins. maybe a could do a larger w/c. or will the gac remove it?

im not too worried about the stn. if i cant stop it ill frag the coral. ive done it before and im sure ill do it again. ):

no signs of any more cyano. thats good. i will test phos and nitrate again either tonight or tommarow along with refreshing my gac.

 

[mos90]

here is something ive been meaning to ask about skimming.

how heavily should i be skimming? i empty the collection cup every few days when it gets about 1/2 full and i clean it out once a week. the cup is about 6"x6".

 

[Randy Holmes-Farley]

Yes, cyano is a big soure of toxins in the ocean, enough to kill many animals and even people.

It's hard to judge skimming, but taht seems reasonable.

 

[mos90]

Yes, cyano is a big soure of toxins in the ocean, enough to kill many animals and even people.

i didnt know that.

 

[mos90]

Update.

Tested tonight.

No3-.75ppm.
Po4- 0 ppb Hanna. .02 redsea pro.
Alk-155ppm Hanna

I'm wondering if I should back off on the no3po4x to 6ml per day and raise alk slowly to 10 dkh. Keeping parameters a little more towards redseas "accelerated growth" recommendations. I dont mind corals a little browned out if I can get some good growth.

 

[bertoni]

You could try that. Our measurement equipment generally isn't precise enough to be all that useful at low levels like 0.02 ppm, so I'd be cautious. The real level could be noticeably higher or lower.

 

[tmz]

It's a seriatoproa(birdsnest) .imo. Looks like an "ora bird of paradise", quite hardy and a fast grower. Don't see the stn in the picture.

 

[mos90]

that picture is a few months old. it is definately stning. im hoping to slow it down. for a birdsnest it doesnt like a ton of light.

bertoni. so what do u recommend i do. should i feed more reef energy daily and see what happens?

 

[mos90]

your are definately right tmz.. it is a seriatopora caliendrum...

 

[leventis72]

This product contains Methanol Randy that was the only ingredient on the box

 

[mos90]

it definately smells like methanol.

 

[Randy Holmes-Farley]

Yes, it lists methanol on the label, but it may also contain other organics. Methanol may just get listed due to toxicity concerns. The company claims it contains multiple organics.

 

[mos90]

should i trust my readings? im sure they cant be too far off. what i mean is, if redsea test kit says .75ppm im sure its not 5ppm. and the po4 test kit can is definately accurate enough to tell the difference from lets say .04 to .1ppm

so i think its safe to say that i am under ..1 ppm of phos and 3ppm nitrate.

now i could be at .01 phos and .25 no3. that puts my in ulns territory. i think thats what bertoni means by be careful.
