Radical new treatment for AEFW

[bknapp]

That I don't know.

Had a good sized cluster on the bottom side of one that got knocked off during acro removal.

 

[Squamosa]

The worms won't affect the montis but they will lay eggs on the bottom side.

All Monti's were checked and dipped....no eggs!

 

[slojmn]

Here they sit, for a month.

Will dip again in 5 days

Wow, Great job fighting the good fight. I did this a couple of years back. Did exactly what you did. I left my tank acro free for 10 weeks...I did not want any chance of getting them again. So far so good!!!

How long do the eggs take to hatch?

 

[Squamosa]

Here's a video I made of the dipping and the worms can be seen coming off after 15 seconds, there were hundreds in total.

It is a 30% Bayer solution and coral was left in solution for ten minutes, swirling occasionally.

How long do the eggs take to hatch?

They hatch out within 14-15 days (at 27C)!

My tank is at ~25C so add another day or two apparently.

Then, it does not make any sense to dip the acros every 5/7 days. Since it takes at least 10 days to reach sexual madurity, it would be enough dipping the acros every 3 weeks to make sure you kill adult aefw before they can lay any egg.
I think that 3 dips would suffice, plus an extra one just in case... that would be a 9-12 weeks treatment.

^ But if you have eggs ready to hatch very soon after the first dip, you could potentially have new eggs in 10-11 days. You want to stop those potential hatchlings before they get a chance to do that.

Eggs are [;aced by adult FW everyday and some hatch a day after you dip and days after that, there's is really no schedule for new born FW.
They are just as bad as Terrorist in our world, no place for even a trail.
Coming back to FW lol............ if eggs hatch a day after your dip they can be a adult within 5 to six days, that's why you want to dip every 5 days to break the cycle of new eggs.

Wish we could get that clear Bayer solution here in the States, would be so much easier to see what's going on.

@Diesel I've been dipping every seven days, would this be a potential issue?

No not at all, just finish the 8 week schedule. Better save than sorry.
In my case the schedule didn't hurt or discolor the corals at all for the 8 weeks.

One of the things I do not like about Bayer, besides being poison is it mixes up cloudy, and I cannot see the AEFW come off the coral which is why I prefer Revive.

I use Bayer and dip in a clear container. If you hold it up to the light and look through the bottom you can see everything that comes off the Acro.

Eggs are placed by adult FW everyday and some hatch a day after you dip and days after that, there's is really no schedule for new born FW.

That might happen, yes...You are right, we'd better dip them at least every week, specially the first dips.
As adult die I think we could separate the dips in time.

Time for an update.

After day 7 it became too difficult to keep the water quality up (even after doing 70% WC's every 2 days) and keep temperature swings small! So I came home one evening to RTN in almost every coral!

This resulted in the long process of removing colonies and trying to save frags from everything.

Fortunately I was able to save frags from almost every single colony I had, but all that's left now are about a dozen frags and some pieces in the tank (acro's and monti's).

I took the opportunity to redo the rockscape and I actually added double the amount of rocks.

I have been dipping all corals every 5 days and the last 2 dips have yielded no worms at all with not an egg in sight

One more dip to go and the cycle is broken, although I think it already is.
Happy days ahead from this painful episode!

 

[bknapp]

Sorry to hear about the RTN issues. Keep fighting the good fight.

This is such a sad event. I lost a 180 gallon tank full of them. I chose to dip some of the rocks at the same time and was pretty successful. I even had a major rebound of my tank until something took every single SPS i had.

This tank thrived despite having ‪AEFW‬.

I used a turkey baster to blow on the corals and sucked them up with the baster. Some of my fish ate them as they flew off. I am not saying this method will work for all but it enabled me to maintain a thriving reef tank despite the problem. This article has more info.....

I intend to add carbon to the water after the water change to 'mop up' any residual chemicals.

I really don't know, but I'll speculate that the bacteria won't be affected and I intend to do the water changes with fresh NSW and any bacterial die-off would be replenished.
I would be more worried about alk, ca and mg fluctuations from the calrx.

Ive used the american bayer here in aus evan traces of it in the rock plugs (after being rinsed twice) killed every pod in my tank.

 

[cjsreefaus]

Use rx coral pro. Much more affective

 

[Reefnjunkie]

Use rx coral pro. Much more affective

While perhaps more effective at not killing pods, extremely harsh and not forgiving on many acros IME-

Pods are easily replaced killing a prized echinata not so much
