sick corals

Can anyone help with this??

In the last week, I have lost one frag, and 3 others are not doing so well. Luckily, they are frags- or unluckily. I don’t know the name of the sps that I lost, but I do have before and after pictures of him. He died in under 2 days- didn’t even notice it. My blue tort is slowly turning to white, starting at the base. This has been progressing for about a week. My Stylophora that I got at the frag swap seems to be sloughing or flaking away. This has been a slow process since 2-3 days after the swap- almost 2 weeks duration. The last one that is notably affected by something is my toadstool. He has not opened or even feed in about 3 days. Also, there are a few zoa frags that have not opened since I got them which was one week before the swap- about 3 weeks ago. My birdsnest frag’s tips were not well a few weeks ago, but I moved him and he’s doing fine now.
Those are the frags that are not doing well. Everything else seems to be fine and growing. Noticed a few new polyps yesterday and my fine grape coral slit over the last week.

Water parameters as of jan 29
30% Water change (jan 17), trates- 0ppm, Ca- 440-460ppm, ammonia- 0, trites -0ppm, pH- 8.2, specific gravity-1.024. don’t check temp.

Set up
It is a 29 gallon display with a 15 gallon sump. 4-22w T5s (2 actinics and 2 10K), lights are on for 12.5 hours/ day. Skimmer (forgot the brand last cleaned 8/07). Using a Koralia 2 (400+gph- just changed at the swap). Using a large 300 micron sock and bio balls for filtration. There seem to be excess detritus- is settled at the bottom of the sump and some floats on top of the water. Will wash or replace sock this week.

Stock
I have a 2 in sand bed 40+ lbs live rock. 20+ different coral frags (zoas, sps, and lps). A gold stripped maroon clownfish, Dwarf angel (cherub- has never nipped or bothered any coral- just the clown at times) and a small green chromis. Will be swapping the clown and angel for a pair of percula clowns and a crocea clam soon. Several blug legged crabs and snails. A few tiny serpent stars, asterina stars (I am bad at spelling, but the really little white ones), and a lazy brittle star. Several small feather dusters.

Feed
KentMarine coral excel daily and frozen twice weekly.

What should I do about the sick corals??? I have looked at the thread started by Fishdoc for sps. Have not been able to see any AEFW or red bugs. Should I just dip in lugols???? Or do a freshwater dip first??? And any good suggestions as to how to catch my angel?? He is fast.

Sounds like you have a bit of RTN running through your tank... It can progress through out your tank moving from frag to frag... Something to do with Mitochondria or whatever... Fishdoc would be the best to talk about that... Though that shouldn't affect your toadstool...

Just curious, why don't you check your temp??? Temperature swings can be the culprit... Especially now with it being winter time... The tank cools down fast without the lights on...

Another thing you might check is phosphates... Especially since you have a detritus build up...
 
thanks ct. I just talked to chris about it. I don't normally test for temp when i test other parameters. I did for a while and it always read the same. Tested with lights on and off, for 2 readings. That stayed the same so I stopped. Will start again. After talking with him, I think I should test my alkalinity, phosphates, and temp. And yeah, it does looks
like RTN. Didn't think that was it because of the toadstool, but he said it may be shedding or just being a softie. Will check them today and post results.
Thanks ct and Fishdoc
 
These thermometers are worth their weight in gold... Well, probably worth more since they're pretty small... :D Good thing they're cheap... If you don't have one, I would get one... Its nice just to look at your tank and know what the temp is...
But you'd be amazed at how much of a swing your tank can have temperature wise... Alot of times the elements in your heaters can vary 4+ degrees between turning off and on... Sometimes they even get stuck on or off, thats why a lot of people have temperature controllers...

Thanks everyone for your help. It was a case of RTN, and I think temp was the problem. I had my water tested at the aquarium, and nothing as really abnormal. I am using a heater and am closely monitoring the temp now to prevent any further damage. Temp was fine until recently-- due to a high KUB bill, my room mate cut the heat off and the temp got really low.
Here is a list of what I lost: un named small green frag from fishdoc, blue tort, green stylophora, green bird’s nest, Garf fuzzy green mille, pseudo leng si cap, pink bird’s nest, and a toadstool (?????). Oh, and I haven’t seen my green chromis in a week. Everything but the un named green frag and toadstool are still fightingâ€"but it don’t look good.
 
That sucks... :( You may not have lost the toadstool yet... Unless its turned white... :rolleyes:
 
Well.... I learned from this experience. Not sure about the toadstool, it hasn't changed colors or anything (always was a light pasty white color), but has been closed for a awhile.
 
Yeah I would give the toadstool some time. If it hasn't melted yet it might still pull through.

Have you tried to frag the survivers? If you frag ahead of the RTN where all of the tissue is still intact you may ba able to save them. I had some RTN running through my 240 a couple of months back and I was able to save all of the corals that had a problem. The fragging of these corals also seemed to stop the outbreak. I hope things work out for you.
 
Thanks. Most of the ones that were/ are affected were frags, so i didn't have much coral to frag. I did with one of my larger corals, and he is doing well. It appears that the the problem has been fixed and the spread has stopped-- more the moment. The affected frags are still extending their remaining tenticles (I guess thats what you call them) and the toadstool is showing signs of life now.
Still wanna get a frag of the birds nests and fuzzy garf from fishdoc.
 
tentacles = polyps :)

Glad to hear things are looking up. I'll get you a piece of those 2 you lost sometime.
