RPS all-out... take 2 !

[kaserpick]

So 35 days in and no babys yet. Interesting for sure. Doesn't seem to be much activity in there lately either.

I agree; very interesting.

Even if they do hatch this time, perhaps in the next experiment, keep the same dosage, but dip again, after 2 weeks? All adults would be dead, and the eggs would be in 'limbo'. Then you could possibly kill them with the second dose. Again, this is assuming they do hatch.

some changes today !
some eggs gone, some seems to have hatched or at least are not intact anymore...

notice the green algae is gone too...
I see two possibilities :

- eggs hatched
- snail wandered there eating the algae and breaking some eggs while moving there...

will see what happens with the remaning eggs...

Ok time for a 24 hour live feed

 

[Acronic]

Live feed would be awesome!

I suppose you could dip the piece again and see if the babies fall off?

 

[jgraz]

If they hatched you would still see the casing like the other ones. Almost seems like they were scraped off.

I agree

 

[Andre@ReefAquat]

Interesting indeed, so there is some hope ? Any further developments ?

Seen this on another forum:
AEFW life cycle:
I allowed a frag plug with a lot of AEFW eggs on it to hatch and grow. It appears that AEFW have a very long incubation period - 3-4 weeks. It takes another 2 weeks for the AEFW to reach a size where they start munching on corals (about 1/8"), and about another week until they are mature enough to start laying eggs. By 4-5 weeks, the AEFW is reaching old age, and it appears that the adults all die before their eggs hatch.

agreed, but theses two look like they might have hatched with the "under" casing still intact...

not much change today :

a planaria is lurking near the eggs...

 

[flamron]

What if the gestation period depends upon how close the coral gets to the eggs? It seems like they waited a long time to hatch. That would make sense to me since the small AEFW are probably not going to get too far in the oceans super high flow looking for food.

Just a thought.

 

[asylumdown]

Part of me wonders if they eggs didn't hatch way back when those white dots appeared on them, and what we're seeing now is just how the empty eggs get from looking 'just hatched' to the empty husks around them? If they have hatched, one would expect that the flatworms would now be munching away on the coral they hatched on to.

Anyone know how long it would take for a flatworm to grow big enough to notice falling off during a dip from the time it hatches? Assuming this coral isn't being colonized by flatworms from somewhere else in the system (I know that's a big assumption), you should be able to tell whether or not these eggs have hatched by re-dipping it in a few weeks to see if any more adult flatworms fall off.

any updates

 

[aqua80]

not much changes since may 1...

that's a point for the "snail thesis" about eggs disturbances (vs hatching)...

 

[BBLINKS]

Tagging along. Thanks so much for doing this. Feel like the whole reefing community is pearing over your shoulder on this thread. keep up the great work.

 

[aqua80]

Day 48, no changes on the eggs, but I had to terminate the test since I was loosing some frags from aefw in the frag tank (they were already there before I put this piece in the frag tank) and decided to dipped everything and get the eggs out...

I started a new tank this winter and I don't want AEFW to be in that tank too...
Anyways I feel that the eggs had reach a point were nothing was going to happen... these eggs were probably laid 50-60 days ago !!

please feel free to post your thoughts/pics/experience with RPS all-out...

It's hard for me to say. So far the DT is clear again after pulling all the known infected pieces of the rocks and dipping them. I need to do the same w/the frag tank now. However I ran out. My efflo for the first time in who knows how long is actually showing a return of colour. I'm not quite ready to re-glue stuff down though. If nothing returns in another 2 weeks I will. I wish I had another bottle, but decide to order bayer instead this time. I think it's a great product but the cost to volume ratio is a bit high. I got 3-4 dips out of the bottle, had it been full maybe I could have gotten a 5th. I may still just order it again as I did like how it worked and just keep the bayer in reserve as right now I don't have anything to dip corals in and have a single piece showing signs in my frag tank.

Any updates?

I started my test 4days after the Original poster (Simon) . My test was alittle more controled as I had dipped the SPS effected with AEFW and eggs and placed it into a clean QT.

I did not have the equiptment to document the test with great pics but I will share my results all the same.

Yesterday I removed the SPS from the QT to see if there were any AEFW or eggs .After dipping I found NO AEFW were to come off , concidering the infomation that has been given in this thread I belived that the hatched eggs would have been mature adults by now.

I dont think that this by any means is the be all and end all test. For me it answered my questions.

The dip seems to have done what it claimed to do, will I stop QTing new corals NO...

Hope to see others results/experiances

My experience was that I dipped everything that arrived in my tank with this dip. I didn't exactly follow the exact instructions though, I always added a bit more than what was recommended. I still ended up getting AEFW somehow and dipped everything. After a few months I thought I was in the clear with everything growing mad crazy and then all of a sudden I started to see some pieces color down and lose PE. Took me a while to notice the bite marks. Took every piece out and dipped again and man oh man there were TONS of AEFW! About 200 I'd have to say. Big ones to little ones! I was really shocked and a bit scared. Was sorta tempted to throw everything away. I was really thorough with that dip, dosed a bit over done and left in the solution for a good 10-20 minutes. The only piece I lost was a small echinata frag, but my large echinata made it through fine.

About a month down the road I noticed about three pieces that still weren't coloring up very well and gave them another dip. Found 2 small AEFW.

My guess from this is that either the dip isn't as effective as it might be or the aefw are laying their eggs in the rocks and under the glue where I pop the frags off.

The product might be harsh on some pieces, but I haven't had any casualties so far using it minus the echinata frag (it was weak when I dipped it to be fair). Haven't tried deep water pieces yet. I do love this dip as it's very very gentle on other corals, amazing for zoas. Kills things really fast too.

If this could really kill the eggs, then perhaps the QT process could be easier and faster. Simply dip. Put inside the tank, but in a small container so the water between the tank and the new corals don't mix, but they can share the light and temperature. Monitor for a week. Dip again and place into the tank. Double dose hitting the eggs at different stages of maturity and less trouble. Just a thought...

 

[rtbm]

Thought I'd revive this thread.

Interested if anyone else has had any indication that what they claim is true.

I noticed their bottle still says "eggs" on it
