AEFW Chronicle

congradulations on your AEFW victory.I have a couple questions if you dont mind.1.How long were you dipping the corals before putting them back in quarentine. 2. did you have any losses from the treatment. 3. did you remove all the acros from the live rock where they may have been encrusted. 4. did you run a skimmer and or rock in the Q tank. TIA

1. I dipped the corals in batches. Each batch was dipped for 20-30 min. in plastic containers (pictures in the thread) and then returned to the QT

2. All of the corals browned out; however, I only cost one coral and that was because I threw it out due to the number of eggs on it. I did have to frag one of the other corals (purple monster) because it STNed, but the frag is still alive in my tank today.

3. I removed every acro from the tank and even several corals that weren't acros like my pink pocillopora just to make sure. I also tried to remove encrusted pieces of the coral from my rock with a bone clippers. Luck for me, my tank was still young and I didn't have any corals that were heavily encrusted on the rocks.

4. I ran a canister filter with carbon and bio media, a small protein skimmer, a small heater, and a moded Maxijet. The protein skimmer stopped working about halfway through the process so I just left it off. I didn't really notice a difference with the skimmer off.

I hope this helps you. If you have any additional questions please feel free to post them.
 
thank you for the response.I really have not seen any flat worms or eggs in my tank but i have been having some unexplanable stn at the base of some of my acroporas lately and it looks like the damage AEFW would do.I will have a coral encrust the frag plug and then when it reaches the live rock it will slowly start to recede.I had AEFW a while back and did the treatment for 5 weeks but returned the corals back to the display after each dip.I now fear that i have some juvinile worms just starting to eat at the base and i want to catch it before i have a full blown epidemic.the area of necrosis will sometimes have a cottony mass appear before the stn starts.other then that everything in the tank ig growing and has pretty good color.prior to the first AEFW problem i had my acroporas would encrust the rock work quickly and form large bases.now that is not the case.any thoughts

Are you seeing any of the traditional bite marks on the receding portions of the coral?
 
well its hard to say definately,but it is a jagged recession on some.no oval bare spots above the recession like i have seen before.

Have you tried taking a coral out and dipping it yet?
 
yea and i found no adult flat worms or eggs.it seems that if i have them they are very tiny and not big enough to see at this point.

Hmm..that is very interesting. Have you checked the rest of your parameters?
 
yea religiously.i wish it were a parameter problem.this happens to acroporas only and healthy ones that are encrusting and growing fine.i will notice a small thin line of recession at the base and it will take a week or 2 for it to move a half inch.if i cut the coral and glue it to a plug it will encrust the plug for a while and then start to recede for no apparent reason.alk is 9.9 dkh,cal is 425,and mg is 1350.phos is .02 and nitrate is .3

That is definitely a bit weird. What are you using to dip the corals and for how long are you dipping?
 
revive for 3 or 4 minutes.when i had adult flat worms they would curl up and fall off within the first minute or so.i dont know, i am at a loss.i have been keeping acroporas a long time so i am no rookie,but i know something is not right here.my corals used to encrust the rock and sprout new branched from the encrusted area and now some of these same acroporas will encrust a bit then stn back.its like the new growth is being eaten by something.just as you would see with flat worms but what ever it is ,its not large enough to see.i am hesitant to do the treatment because 30 out of the 40 acroporas i have look fine with no signs but i cant just sit back and watch this any more.

Yeah, I can definitely understand why you would be very frusturated with this problem. Have you noticed it spreading from acro to acro or has it consistently remained on certain acros? Also, have you tried posting on the SPS forums on RC?

I found this link online also and thought it might give you a place to research a bit more:

thanks for the link,it was informative at the least.i tried posting about this about 6 months ago with no real answers found then either.i have 2 options at this point i guess,do nothing or do the treatment.i will probably wait a week or 2 and if it continues i will do the treatment.

I think that's a good plan. I would wait for about 2-3 weeks and then dip one of the worst corals again. By that time you should be seeing adults for sure if you have them.
 
Verify that your salinity is right. I had something similar happen, and my refractometer was reading 1.026, but was actually 1.021. I was using RO/DI to calibrate it, instead of 35ppt calibration solution. That was a dumb mistake that was quickly corrected, <b>after</b> losing a number of SPS for no (good) reason.
 
UPDATE

It has been a little over five weeks now since my last dip with TMPCC. All of the corals have been moved from my QT back to my display tank. Since the move I have seen zero signs of AEFWs. All of the corals have started coloring back up nicely. I didn't end up losing a single frag/colony to the dipping process except for the one I threw out because of the number of eggs on it. I will update this thread again in a month to confirm that my tank is still AEFW free. I will also try and provide some pictures in my next update.
