flat worms

[asylumdown]

Taking the rocks out one by one to dip them sounds to me like an awful lot of work that increases your chances of the product failing overall. Those little buggers can move fast when they put their minds to it, and you'll never get the worms that are on surfaces that you can't remove (overflows, return lines, sand, glass, etc.).

I know there are horror stories out there, but there's also thousands of successful applications. I've used it twice in a full blown SPS reef and the only negative effect was the loss of a single acans colony that caught and ate too many dying flatworms. I'm sure I could have mitigated that by actually siphoning some of the worms off first, but I had grossly underestimated the number that were in the tank.

The first treatment didn't get them all (there were literally millions of them), so a few months later when I noticed the first 10 worms I dosed again. The only side effect to that treatment was that I no longer have any flatworms.

Obviously not saying you should or shouldn't use the product, but when you have a system wide infestation, I think you either need to treat the system, or go with another method of control.
