I am very interested in seeing you do this. Do you know if you can see eggs? I have no idea if the AEFW lay eggs in the same place all the time but watching to see if eggs disappear might show the adults are dying.
I can't find any eggs but they're somewhere!
The whole idea is not only does it kill those alive, but two doses in the first week destroy the breeding cycle. Then they take about 14 days to reach sexual maturity, and about 6-8 days to hatch. So the two follow up treatments kill them before they can breed. By the third week it should be completely eradicated. I'll probably dose 4 weeks just to see..
I used a product you might get in the States, Dettol over here is a household disinfectant, kills most things but I still have to watch for eggs hatching if I miss them.
What makes this special is it's an in-tank treatment. Melafix is a nice dip, but really I need a mini coral QT at this point... Like a 10 gallon QT.
