The problem will continue to grow until we hold the supply chain at least partially responsible for the corals they pass down the line. This won't happen of course and nothing will change, except it will get worse, until the consumer holds his hand up and says, "I won't buy your corals if they are not clean". This problem is far more severe today than it was 10 years ago, what can we do to make it better in the next 10 years? Do we even want to or are we ok with letting it get worse? I can certainly see the next wave of marketing being "Certified Pest Free" and yes it will cost more and people will pay it. I have been fortunate to personally know a lot of LFS owners. I only know of one who would be ok with selling corals with pests. The other dozen or so would want to know because good LFS's understand the power of word of mouth and actually care about the hobby, it is their living. How much does it really cost us to treat our corals before going in our system? For the LFS it would not really be that expensive and in the long run cheaper than bad publicity and a marketing strategy that would pay off. Would you prefer to buy corals from an LFS that you knew treated before the sale or one that couldn't care less? The LFS is absolutely responsible for the corals it sells, just as we as individuals are responsible for the corals we trade or sell.
Ultimately we have the responsibility for what goes in our tanks. To anyone who is living with AEFW now, would you like to go back to that day and not put that coral in your tank? My guess is you would. If you got that coral from someone you know, and they knew it was infected, and didn't bother to tell you, would you be ok with that? If you bought that coral from a supplier who knew it was infected and did nothing to stop it, would you really be ok with that?
Maybe I am just wrong for wanting to see this problem get resolved. I can say that after tearing apart a very well developed 6' tank loaded with acro's to treat for red bugs once, I will do whatever I can so that I never have to do that again. I was not ok with treating in the display and risking the loss of an established pod population and biological filtration. Removing the acro's was the only way to achieve my goal. I may not get the flavor of the month coral but I also won't be risking the corals I already have just to get the latest and greatest.
We are responsible for what we put in our tanks. If you cannot trust in your source, you better be ready to treat your corals and QT them. The problem will not go away by itself. I agree we need an in tank treatment that works, but we don't have it yet.
