Many don;t know they have anything when they trade. One person sells 50 frags to different people at a frag swap, then they trade... It's exponential...
I agree gflat65.
I have had them 2 times, from frags, I have always done a dip and QT and since I got them the first time and now I have them a third time. It's like an uphill battle and for the most part I don't think this hobby will ever escape away from this problem, if it really is one.
As with the first 2 times I have noticed no ill effects on my corals, but because I read so much I though I should kill the SOB's as quick as possible and I did. Each time I treated the tank 3 times at double the dosage over a period of about 15 days. Each time I killed them all along with all of the shrimp, hermits, snails, acro crabs and pods that I couldn't get out of my tank.
This time around I can't treat, I just had major surgery and walking is hard enough right now let alone doing 3 major water changes on a 180 (most of my corals are encrusted onto rock so taking them all out and dipping and QT is not an option). I can't even lift anything over 20 pounds for the next 3 months.
So far I have had no ill effects on any of my corals, in fact the are growing just as fast as they ever have and there have been no loss of color. I will continue down this road until I am able to treat however if nothing changes between now and then I will not treat. I am not going to kill off all of my shrimp, hermits, snails, acro crabs and pods that I can't get out of my tank for no reason EVER again. If I do go down the don't treat road I will be responsible and keep my frags to myself or let those who want frags from know that they will need to treat them for red bugs.
In recent months I have noticed other reefers taking on the same approach so it will be interesting to see how all of this truns out. I know for a fact there are some reef keepers that have had them for years and they have no issues at all.....
Just my opinion based on my experience.
