What is my milli doing

[lokii_37]

I picked up this milli frag on Sunday from the meet. I dripped it, dipped it, and then added it to the bottom of the tank to get used to the new conditions. Everything else in the tank looks good even other frags I picked up the same day.
what should I do? Will this have negative effects on the rest of the tank?
Cal 410
Akl 9.4
Mag 1360
pH 8.2
Temp 79-80

Its RTN.....rapid tissue necrosis. It already looks pretty bad, take it out of the tank or it will sour your tank. Itmy guess is you left it in the dip too long or you made to strong of a dip.

That frag is done for. Yank it.

Your water parameters look good, BTW.

Lighting, phosphates and nitrates?

 

[lokii_37]

BummerI was thinking it was RTN. It's been yanked

Lighting 6 54w t5s over 75g
Phosphates 0
I'll have to check nitrate. I have a tiny bioload

Yah that one looks pretty rough. Yank it. What dip,cocentration and how long

 

[lokii_37]

I dipped it in provadone. 2ml/liter eight minutes I was worried I didn't dose enough.

 

[Reef Bass]

You are correct that is less concentrated for less time than the recommended concentration and time for povidone iodine. The club's iodine handout recommends 3ml/l for 25 minutes for acros.

The numbers are lower than recommended but the providone is probably the harshest dip for the corals that I have ever used. Those results are why I changed over to Melafix. In my experience it seems to give the same results and is far less harsh on the corals. I still use providone but more of a last resort for say an lps that is receding and I want to try and stop the infection from continuing to progress. I see a lot of people using coral fx and a few others but I hav'nt used these. What experience have the rest of you had and with what products?

There are several thing to think about when you add corals. They are much more sensitive than fishes so you have to consider:

1, Salinity (if different then you have to drip your tank water into the corals water until it matches
2, Temp make sure themp is matched by soaking the bag for atleast 15 minutes
3, dipping (I would err on the too much dipping and kill the single coral instead of infecting ym whole tank)
4, Is your tank ready for sps? (maybe test it with something hardy like a green slimmer first and see)
5, Alk, some tank run higher alk and some runs lower so dripping is good because if Alk spike on a coral then it will suffer
6 ... anyone have anything else to add?

Looks like a fresh cut frag, the plug looks brand new
I don't think it was the dip

 

[lokii_37]

Thanks for all the info guys. Everything else in the tank is looking good, including a few other sps.

 

[Reef Bass]

Tom's list of major factors when corals switch water systems is good. A lot of people think about temp and salinity, but I think many get tripped up by #5 (large difference in alk between environments). I do believe in dripping which can, imho, reduce the stress of the change by making it more slowly. However, if one has a difference in alk of several points, that's going to be stressful, even with dripping.

I use a three dip method. First Marine melafix used as directed on the bottle for 5 minutes. Then Brightwell Medicoral dip for 5 min. Then put the corals into a white bucket with some water from the tank for another 5 min to obsereve for any lingering pests. Then into my QT tank.
