There is a local in town that I help with his SPS tank. He has some special needs and is not the best QT or dipper (generous... he never does) and he got some AEFW. He bought the big jug of Zeo Flatworm Stop and has been doing a double dose for about two months. Even in his most infected colonies, there are still flatworms, but we are not seeing any more eggs... anywhere. Does anybody know how long a acro eating flatworms can live? I know that folks have routinely posted that the Flatworm Exit has not killed the worms, but is it possible that it will interrupt their lifecycle with continued use and eventually the lack of reproduction will rid them? Has anybody used this for long enough to know? Has anybody else experienced this? He does use it at double the recommended dose. Thanks in advance.
