AEFW: In-Tank Whoopin

Risky, but it might be OK. They can be eaten by things too... damsels and peppermints can get them. Some have reported that some wrasses will crush them - especially Halichoeres.

I have a pair of yellow wrasses, and adding a Melanurus this Saturday. I dipped a couple things today as a precaution and saw nothing, no eggs, adults, nothing. I'm praying I got this early on and instead of putting the affected ones back, I tossed them. I don't want to take ANY chances.
 
Thanks guys for doing this, great work. I am not at the everything is dead anyway point, at least not yet. Got to beat the head against the wall a little longer.

Fwiw, Bayer is just another dip IMO, ran some experiments with AEFW and Bayer, definitely helps to knock them off. However the fw I have uncurl then come back to life when removed from the dip and put back in tank water.
 
This might be interesting to some. An AEFW in 3x baseline Lev dosage since 2 hours:

Its a bit shaky since i had to move the container around to get the AEFW in frame.

Its not the most healthy of specimens and is very easy to baste. But its still alive.

Size comparison is 1 swedish Krona. Look it up ;)
 
JDA.... thank you for sharing your work!

Ormet.... thank you for the updates on you trials.

Having battled AEFW through removal and dipping an intank solution will prove a god-send to the hobby!

Hi Brent, I live in Socal and thinking of getting back in to the hobby after being out of it for several years. Could you please drop me a note here on PM.

Thanks,

Scott
 
Just to add to the discussion. I am close to transferring all my acros to my upgrade from my temp tank. I treated for AEFW over a year ago using the Bayer method. Everything was great, but recently I suspect I may have them, but I have not been able to confirm. That said, I want to eliminate any doubt, so I was thinking of prophylactically treating for them using this method.

Because all my acros are in an established 30 gallon, I was thinking of using a hybrid method. I have a spare 10 gallon tank I can coordinate a largish water change and treat the acros in the 10 gallon as an extended quarantine. I can add an air stone, and a couple of power heads and even an HOB I have lying aroud. After the 24 hours, I can transfer the acros straight back to the 30 gallon. My thinking is that this will minimize the die off effect. I realize that I miss some free floaters, but could repeat this a few times and do one last Bayer dip before full on transfer to my new build?

Any thoughts on doing it this way? Or should I just nuke the tank? I am carbon dosing so I will need to back that off.

If you are transferring inhabitant in the near future maybe just nuke the tank as the die off wont cause lasting issues due to tank transfer. In the short term manage the effects of die off with carbon and large water changes...its only 30 gallon tank after all.

Thanks. My biggest concern was my carbon dosing. What I may do is first transfer most of the fish so I can remove a lot of the import. Without the carbon dosing, my nitrates go way up which causes problems. Once I transfer most of my fish, I can ween off the carbon. I don't want to ditch all the fish, because last time I did that, everything paled out big time. I do want to nuke several times to be sure, so I figure this may be several weeks or more to finish the treatment. Anyone else have an opinion on this? Gonna order some Prohibit this weekend. Wish me luck, LOL!
 
Ormet - thanks for the video update.

Is the video taken 2 hrs in the 1st treatment or is it after it survived the 1st treatment?
Just curious about what you did to kill that fw - did it die eventually?
Are you going for the 2nd treatment with the same dose?

This one, among with several bigger AEFW did survive the first treatment.

I caught three, but saw several more, during this second treatment.

2 i put in 10x strength, after 20 hours in baseline (baseline dosing according to jda's recipe if you will is approx 2.8mg/L)
They died after 10-15 minutes. It was quick.

The one in the video died after 6 hours in 3x strength (and 20 in 1x)

Bigger ones need higher dose or longer exposure then small i think. Need to do more testing really.

I will up the dose to 5mg/L next treatment. Some of my acros show signs of bleaching tho so i will be standing by with GAC and water changes.
 
Just wanted to know your dosing program for your tank treatment, appreciate if you can elaborate.

Is the 1st treatment dose at 1.5ml/gal and that was the baseline ?

1.5ml/gal should be 0.39ml/L, so baseline is 0.39mg/L - hope I did it right since I have to lookup the gal to liter conversion factor.

Are you into the 2nd treatment at 10x baseline which is 3.9mg/L ?
And you're planing your 3rd treatment at 5mg/L which is 12.8x baseline ?

I'll give it a try. Math is not my strong suite i'm afraid, and the Gallon/Litres conversions makes my head spin.

Baseline, following jda's dosing/log:
1 tsp, lightly packed = 3.5g Lev powder kind of extrapolated on my gram scale. My gram scale have no decimals but it did go over to 4g with very very little extra powder. So lets say 3.5g for now.

3.5g in 500ml RODI. Dose this 1.5ml/Gallon = 0.375ml/L

I dosed just a hair under 1dl or 100ml into my 250L of water.

And this is then how i did my math = 1dl = 1/5 of the powder. 3.5 / 5 = 0.7g of Lev in my tank.

0.7g / 250L = 2.8mg/L or 11mg/G

Recap:
Treatment 1 @ 1.5ml/G
Treatment 2 @ 1.5ml/G
Caught 3 AEFW during T2 between hour 18 and 20
Put 2 in a bowl with 15ml/G = death after 10-15 minutes
Put 1 in a bowl with 4.5ml/G = death after 6 hours
Treatment 3 (in 2 days) @ 5mg/L around 2.5ml/G solution more rambling will follow.
 
Seems like the higher concentration, the quicker and more thoroughly it kills these buggers. Has anyone experimented with using a super high concentration as a short dip? At what point does it affect the coral? Something to look into.
 
There was a study at K State that concluded that the Lev could kill any worm in reverse proportion of exposure time and dosage - these were livestock worms.. so perhaps it is unrelated, but I kinda doubt it. Coming up with the highest reef safe dose is the hard part.
 
Log dos #3:
2014-09-08 10:00 - Skimmer and GAC offline. Dose 150ml! 0.6ml/L 2.4ml/G
2014-09-08 12:00 - Baste all Acropora w/ small ph, no AEFW.
2014-09-08 12:15 - Baste all Acropora w/ turkey baster. No AEFW :D
2014-09-08 15:00 - Brittle stars are unhappy as usual.
2014-09-09 08:30 - Baste all Acro with ph & tb. No worms.
2014-09-09 09:00 - Skimmer & GAC online.

No worms to experiment on this time. Good and bad :)

Will dose again in a week then wait for a month and dose one final time.
