Using Acriflavine to treat Brook

[Pokerman11]

Using Acriflavine MS from fishvet. It reminds me of working with iodine, but
The question is how long do I need to treat with Acriflavine?

There is no instructions on this bottle other than 1tsp per 10gal and to be sure to top off the Acriflavine to match W/C

The brook (it was brooke pretty darn sure), I'm am treating cleared up within a week of first treatment.

It's been 4 weeks now, the fish seem to have no ill effects from the Acrifavine, but I was wondering when to stop the treatment.

I'll still keep them in the QT for a 6 week observation period.

After 4 weeks, you are likely clear of the infection. I would contact FishVet and ask them what the treatment length is to be sure.

I was reading through wetwebmedia and Mr. Fenner said that Acriflavine isn't effective against Brook:

"Brooklynellosis. Cure/s, rdg. 2/8/12
Hi Crew, I am in a remote part of SE Asia and could not get any medication that would work on Brooklynellosis. All the fish died and the tank now only has a few inverts and runs a natural system of living rock and about 0.5 cm of sand. I therefore cannot use Formalin, I have heard Acriflavine is effective.
"Nah"
Any views of Ruby Reef Rally,
"Is a sham, scam... garbage"
or leaving the tank with no fish for about six weeks to kill the free swimming stage?
"Winner!"
Any suggestions you have would be appreciated? Regards, Adam Aarons.

I have some Acriflavine, but haven't needed to use it. My concern is that the med will knock the Brook infection back and won't eradicate it, if Brook is indeed what the fish have.

Keep an eye out for reinfection and I would add some extra observation time to the tail end of treatment. Let us know!

I think if I ever have to deal with Brooklynella, I would use CP. There are conflicting reports on whether acriflavine is effective.

Isn't Formalin supposed to treat it?

 

[tylersarah]

yeah, but Formalin is nasty.

All I know is what I have seen. I had a parasite that to the best of my ability and a few others on this forum believed to be brook. It was in my reef, the cromis and clowns seeme to tolerate it, but anytime a tang/sturgenfish was introduced they would come down with it. Also anytime I moved a fish from my reef to my FO the tangs in the FO would come down with it.

I finally have had to go fallow in my reef (a major undertaking getting all the fish out)

Cupramine did not have any observable affect. ParaGuard no affect. I watched too many good fish die. I was going to give up on all fish, but found Acriflavine. Whatever I have (it may or may not be brook there is no way to really tell) is controlled by Acrifavine.

Now that all my reef fish are in a QT, I am treating them with Acriflavine. I've had them in it for 4 weeks. Going to now stop treating. They will be in the QT for 12 more weeks. The fish from the reef seem to be resistant to whatever the parasite is, but are carriers of it. I have some tangs in there with them so will observe before introducing back to the reef.

Can't argue with results.

Based on my experience with brook on several fish, I will not use CP for brook again. It definitely kept it under control, but would come back as soon as I ran carbon to remove the CP. Formalin is the only med I've found that's seems to be nearly bulletproof for killing brook, this is just my opinion based on recent cases.

My goto now for all new or sick fish is formalin and malachite green. 1 ml of each in 1 gallon of SW, aerated excessively at least 15 minutes before dipping fish and during the 45-60 minute dip. I like to use the 1" spherical air stones and crank up the air supply. I realize it's harsh and potentially lethal if guidelines are not followed, but I feel much more confident in it than the other methods I've used. Admittedly, I did accidentally kill several fish by not aerating sufficiently and putting too many fish in the same bucket.

What dosage did you use with CP?

 

[todddye]

I used NLS Ick Shield powder at 15mg/l, but I did a second round at 20mg/l and still did not eradicate brook. I do know others that have had success with CP on brook but I did not on multiple occasions.

The issue with CP is that certain bacteria seem to be able to transform it into ineffective or at least less effective forms.
