banshee · Dec 14, 2015

Hi

Tank is a 40 Breeder with a 20 gallon sump running for 3 years to filtrate the tank i am using a vertex omega 150 and for circulation two jebao rw4. Alk and calcium is maintain with a calcium reactor. Also have some LPS and ricordia all doing fine and growing.

Parameters:

Test using Salifert

Salinity 1.025
Alk 8.6
CA 420
No3 0
PO4 0

Same Green acro bleached on the base lights off

I atached some Phothos you can see the some acro bleached in some parts. photobucket its acting weird it keeps uploading the same photo over and over and does not upload all the photos

Here is a photo of some stars i have been seeing lately. Its on the base of the coral

The pink bird nest on the back has its tip bleached and now its healing

This acro has a white spot on the base also

Provide them with no3 and you will see a huge change for the better

I don't want to say it but check for AEFW. Hope it's not. If you can take the colony off and dip it to check if any worms falls off.

I cant seem to rise the NO3 always been battling this problem. I manage to have 10 fish one time and only bumped the NO3 to 1ppm. Currently have 2 clowns, melanurus wrase, mandarin, yellow watcham goby .

Wow i search for them on the internet and are very small. how you found them?. I cant remove the colonies, they are encrusted in the rock. I have a purple bonsai and it was the first to develop the withe spots. The spots are almost identical to this photo from google. The only difference its that mine is full of green polips. I have two more colonies of acro with no spots what should i do?

I need to see if homedepot or walmart carry that item. Amazon wont ship to Puerto Rico.

The round spots you see are bite marks. AEFW are really hard to spot. Try if you can to take the infested colony out with the rock. Cut up all healthy branches and pretty much throw away the base. Dip the branches in Bayer insecticide. I use 4ml per cup of water for 5 to 10 minutes. Eventually healthy colonies will get infested too if you don't take quick action. Even dipping them will not get rid of the eggs. Pretty much you are in for a lot of work. There is also Salifert flatworm exit but I have no experience with it. Some reefers just start a new tank all over again since it's so much work and time to deal with these flatworms.
There are a lot of information on AEFW eradication in the forum. Please read and understand.
Just to really make sure if you have AEFW please try to dip an infested colony. I hate delivering bad news. Wish you the best. Hang in there.

So i have AEFW could not resist the stress and pulled hard on two colonies. Look what i found....

Now i know from what source i got the bugs.

Corals are on the trash can. There is only one colony i cant pull off. If i remove all my acroporporas will the AEFW died eventually?

Reefer93105 · Dec 15, 2015

Those pictures just make me cringe! There is a research done by Kate Rawlinson. Google it. It's an interesting read. I think long enough without an acropora host will eventually eradicate them but how long will it take I'm not sure. Hang in there! All corals have their own pest. It's part of the hobby and learning. It's what makes his hobby or addiction interesting.

That's correct. Removing all acropora from your tank will starve them out. If there's any bits around in the tank or any pieces of the base left they will still be there. I believe it takes around 3 months for them to die out, but I might be mistaken. Another option is to dip them all in Bayer twice a week for 8 weeks. With that method you get to save the acropora.

So if i decide to dip do i need a QT? In order to have one i will need a chiller and a light fixture wich are vere expensive just to save two acros. I only have the green acropora in the photo and a strawberry shortcake wich i will hate to lose. The other ones are in trash can. I think i stay away fron acros until i can set up a QT.

Sorry to hear that

Once I saw those eggs my heart dropped

banshee · Dec 16, 2015

Update yesterday i dipped one acro in iodine followed by a melafix dip but nothing came out of the acro i blasted hard with the turkey baster , later will be going to walmart to get the bayer. I started thinking and the coral that bring the AEFW has been in my tank for a bit more than a year. From what i read this worms go crazy and reproduce very fast I think something is eating this worms. I hope by dipping the corals in bayer could get rid of them.
