Marine Ich

Ok seems as though my Naso Tang came down with Ich.. Kinda a bummer as I figured there were no other fish in my tank so why QT him.. So I added him to the Display Tank Along with 2 Percula's.. Today I noticed what looked like a few White Crystals above the Eye.. I immediately pulled him and the 2 other fish from the display tank and placed them into my cycled 29gal that I was trying to figure out what to do with.. It was just going to be a FOWLR tank so I pulled the LR out of the tank and added it to the main tank... And now I have a 29gal QT tank.. I was planning on using Hyposalinity to treat the disease... I replaced 6 gallons of water from the tank with FW as the article states and it dropped the salinity to 1.020... My question is.. Is there any other disease that looks like white crystals??? Is there going to be anything wrong with adding them to a cycled tank and treating with Hyposalinity??? Should I use Copper instead of hyposalinity??? And are 4 fish going to be ok in a QT tank.. as well as is a NO 20watt bulb going to be ok for this 4 weeks that they are going to be in there??

FISH in 29gal QT tank..

2-2.5" Naso Tang
2 1" percula Clowns
1 yellow-tailed Damsel

The yellow tail was what my LFS had me cycle with.. So he has been in the tank from the begining... I also have 20lbs of sand in that tank.. Should this setup be ok while I am treating Ich.. I dont want any of the poor fishes to die.. One last question... Should I treat for 4 weeks or 6 weeks???

TIA,
James..

Hypo salinity can work, if it is ICH. The cysts will burst if done properly, however, the ICH is in the main tank and if you, lets say, kill the ICH on the fish and put them back in, they will most likely get it again so, it is best to leave them quarantined for 4 to 6 weeks. The 29 gal, you can leave the sand in, or take it out..

I would hold off on using copper right now unless it is real bad... If you can get RO/DI water, I would go for the FW bath first..

I would keep the 29 at full salinity, and then get a good size bowl, fill it with 80% RO/DI water and 20% tank water. The PH should be raised to the same of the main tank, by adding sodium bicarbonate (usually 1 tsp per gallon). Get it to the same temp as the tank, and then slowly lower the fish in and watch carefully. DO NOT LEAVE IT ALONE. Leave the fish n for no more than 10 minutes. Some fish will only allow this for 3 to 5 min, before show signs of stress.. This should be enough, and then slowly lower the fish back in the 29 gal.. Continue to watch the fish for signs of the disease decreasing.. After it is gone in about 10 days, do not get anxious and put the fish back in the main tank.. Let them stay in the 29 for about 4 to weeks... Thsi should get rid of it...

Again, I would hold off on any copper products unless it is entirely neccessary....

Good Luck...HTH

I would use the hyposalinity, but I'm not sure where you got 1.020 as the target SG, it should be closer to 1.009. Here is a good article on >>hyposalinity<<.

Reefrunner... I have read that article and It goes over about dropping the SG down slowly.. I was at 1.025 in that thank and changed 6gals out and replaced it with FW Dropping my SG down to 1.018 now... I am in a few more hours going to repeat with another 6gals of FW and According to the paperwork it should drop it to 1.016.. I will be down to the 1.009... I also decided that all the other fish looked good so I left them in the Main Display Tank and will watch for any signs of Ich on them over the next few days.. My guessing is that the Naso Came in with Ich and If I QT him and keep an eye on the others for Ich.. It should work out great.. If they do happen to show up with it I will slowly acclimate them to the QT as well and start the 4 week cycle then.. I just dont believe In subjecting them to Hyposalinity if there is no signs of them being sick..

Please Let me know if this is ok...

TIA,
James

I wouldn't drop the s.g. any more than a few points each DAY, not hours.

What are the "other fish", just the clowns right?

According to the article... Your starting point should be between 1.025 and 1.027. Replace about one fifth of the volume with RO, RO/DI or aged freshwater that has been well aerated. Repeat this 12, 24 and 36 hours later, monitoring the specific gravity along the way. After the fourth water change the specific gravity should be 1.010 or pretty close. Wait a few hours to make the final adjustment to get down to 1.009. Note that you can estimate the resulting specific gravity. If you are changing one fifth of the water and the current specific gravity is 1.025 the result will be: ((1.025*4)+1.000)/5 = 1.020 approx.
which is what I am working off of.. The other fish are 2 clowns and a yellow-tailed damsel.. the yellow tail was originally in the QT tank so he got moved to the main tank.. and the clowns stayed.. Which from my reading are not as succeptable to Ich as Tangs are.. I observe my fish extremely well to make sure they are ok on a daily if not 2 or 3 times a day.. That way i can catch things like this quick before they become a problem.

TIA
James

Sounds good, a little quicker than I would drop it (I did it over 4 days), but it evidently has had success so it is just a difference in opinion.

I just wanted to be sure of the fish, as it seemed there was a change in number. Your plan seems good, you could always add a little garlic extract to the food for the damselfish (clowns including). There is at least anecdotal evidence that this has helped strengthen immune systems to help prevent or treat ich although I would not rely on it as a sole treatment for the tang.

This makes a good case too for only adding 1 fish at a time and quarantining each one, it leaves out some of the paranoia at least for the "if" questions as to whether the other fish may have picked it up too.

Good luck, seems like you are on it good and early.

Yeah another Newbie learning the Hard Way.... Yet another Lesson Learned.. I have also ordered another 40lbs of LR and another 10lbs of LS to add to the main display hehehe.. For a total of 90lbs of LR and 15lbs of LS.. Well off to check on my Tang..


Thx Again,
James
