Fallow Period

[june torres]

what is the recommended fallow time for marine velvet/ich? can a shrimp or other inverts carry or host this disease? i have my tank fallow now for 5 weeks because of this.

TIA

5 weeks for ich should be good, i think your ok with the inverts too.. i dont know how velvet works..

after you do this, everything that goes in that tank needs to be fallow for a month or so and the fish need to go through hyposalinity which takes 6 weeks or so and that will keep ich out of your tank. (if thats what your trying to do). its a lot of work, i only do it for 1 of my 2 tanks..

I believe it is a minimum of 6 weeks. But I think @AdInfinitum has done a lot with uck and it's life cycle. Possibly know about velvet as well

thanks for the reply. i actually lost all my 4 fish because of this. it happened so fast thats why i actually think its velvet and not ich. im pretty sure it was from the last fish(coral beauty) i added that my tank got it from. in a span of 3 days all of them were gone.

If you are absolutely certain it was velvet then 6 weeks is the number...however if there is any possibility it was ich then fallow period must be 76 days to be certain it is gone. (Yes 76 is a specific number...ich is actually a very well studied organism due to its role in commercial fisheries...contrary to the many vague...voodoo stories and remedies you will encounter on aquarium websites)

Inverts are not suitable hosts so no worries there. Do you have corals in the tank?

I've read on a few different forums that hyposilinaty will kill ich only and not velvet.... also it will kill snails, crabs coral , your live rock etc.... so doing a hyposilinaty in your DT tank might not be a great idea. I'd leave your tank fallow if you have coral , live rock and inverts in your tank....just my opinion.

Its a minimum 6 weeks, and just to be safe I always go 10 weeks. There have been cases where it will last 8 or more weeks. Yes all inverts can stay in the tank as they will not carry ich or velvet. Also after treating your fish it is good practice to watch them in quarantine for another 6 weeks, hypo doesn't always kill ich snd it does nothing to velvet. You need to treat with cooper for velvet. Good luck.

Hyposilinaty should be done in a separate tank though as it will kill the inverts and coral.

Where you can use copper...industry standard treatment is entirely quinine derivatives as they are as effective and do not harm the fish the way that copper does... Chloroquine is equally effective against velvet and Ich. Velvet can survive and reproduce at salinities that will kill virtually any marine fish. Ich are susceptible to hypo but evidence shows that ich has become increasingly resistant to it so it is hard to be sure your strain has been eliminated.

Oops we must have been writing at the same time... so from now on I will say 11 weeks. Thanks.

Forbthose with FOWLER tanks...chloroquine is completely safe for bacteria beds...does not persist in rocks or substrate (so they can be used in reefs again) and it is an absolutely killer algaecide and destroys Aiptasia as well.....

i got no corals at all yet. ive only got inverts atm in my tank. so this "chloroquine" will not harm any inverts and live rock/sand when used? where can i get a hold of this?

and yes im pretty sure its velvet that i got. because when i pulled out my fish it was covered in a powdery white slime coat with white spots too.

thanks for all the input.

I would relocate the inverts during treatment as they are unknown and some would definitely be killed...chloroquine will also kill some praziquantel resistant worms.

The actual drug form is very inexpensive but can be hard to find in Canada. However ichshield powder form is sold for aquarium use by New life and is available from reefsupplies.ca

Every thing I have read says that it will kill most if not all inverts, coral and algae.

some fish don't take well to it either I've been using ichsheild powder in my QT tank and it seems to work well but I have copper on hand for the fish that have shown problems with it. you don't want to over dose because you can kill the fish also don't use the ichsheild pellets you cant control the dose that each fish is getting and you can od one fish ive done it.

 

[AdInfinitum]

There are a few species of wrasse that people have reported sensitivities although some well known wrasse collectors swear by it.

Exceeding recommended therapeutic doses by more than 30% increases the chances of negative reactions however that is a much broader safety range than copper.

 

[june torres]

so i guess the best way for me to do is to just wait it out. im 5 weeks in already and i guess another 6 more weeks wouldn't hurt.[emoji6]

Just for the sake of trivia BTW....

Quinine is an anti-malarial medication and it is also what gives tonic water its distinctive bitter flavour.
