If you have SPS in QT and discover AEFW, what do you do? Suggestions on how to treat to get your QT clean?
Any quarantine fish or coral needs to be built with instant setup and tear down in mind.
In coral quarantine I've found that having 2 small batches of liverock stored in in separate buckets kept at reasonable temp and SG fits the bill.
You bring in corals and put them in quarantine. You put 1st batch in and discover AEFW. You treat the coral and then wash out the quarantine tank and use 2nd batch of liverock. Running 1st batch fallow in the bucket will allow the AEFW or eggs to die since they didn't have a host coral. The 2nd batch, if you notice the AEFW, then repeat. You can isolate and conquer the flatworms this way and know for certain they will not get into your display. The idea is that you circulate the rock to create a fallow period.
The current method I have been using with great success.
I multiple stage dip everything that comes in and all dead parts of any frag are cut away and I remount all frags on my own fresh plugs. This gets the egg possibility completely out of the equation.
And I inspect with magnifiers and a flashlight after the last dipping stage of Betadyne. It's harsh on corals if you soak them, but a quick hit in a 6ml to 1000 ml of tank water turns flatworms orange and lights'em up so you can see them. So far my multiple stage dip has only killed 1 SPS and it was already on it's way out.
I acclimate to tank water first, then dip in revive (soak), levasole (soak), interceptor (soak) and betadyne (baster blast the entire frag for under a minute tops) and heavy inspection everything that comes in. If it does not survive it so be it.
