The purge doesn't kill AEFW, it interrupts the life cycle of some, but it didn't work. I don't see it causing deaths 3+ months after the last dose. Plus no other users have reported death of fish with use.

I think it would be useful to at least ask Marine Collectors what their shipping salinity is.So I spoke with another vendor today who qt's. He said I can't blame myself or Marine collectors. He said the quality of fish that are coming in are not good. Divers are using poison to catch them more, as supply is declining in some parts. In addition fish are not being shipped as quickly due to the lack of direct flights, so they are spending 3-4 days in transport. He is seeing a much high mortality rate when his shipments come in. Then most are treating the fish under qt which is also stressing them then shipping once they are done. He holds the fish for 30 days min now to make sure they have time to destress. Doesn't cover what happened to the og's. In addition he ships 1.023- 1.024. that should work out well, I'm not sure what marine collectors ship in, they don't have it posted that I could find on their site.
After the ICP, I have changed about 200 gallons worth.What about water changes? How many have you done after icp test?
Last week I stopped the kz coral program, and kz fws. I do run a few table spoons of carbon always. I guess we will see over the next few weeks what goes on. I'm not adding any fish for now until things settle.Not finding much to suggest yet that these levels would cause death in 2 week intervals at reef ph. However 10 Ug/l Is considered a "trigger value". I would at least do water change maybe and run carbon If incase A:chromium is an issue B: the flatworms do have toxins C: the flatworm meds do have adverse effects. If you keep losing fish it maybe something else.
I have but would advise against some inverts. Shrimp maybe a definite no. I would also take them out into another tank if unsure. If worried about corals I could provide you with research paper used to treat diseases in sps corals. Also some people use this for brown jelly disease in lps.added that to a reef tank
Tank is full of SPS and some lps. Inverts, shrimp, crabs, snails, and urchins. I think I'll dose if I lose another og over the next month. If all good in a month then I think it's safe to say I'm out of the clear.I have but would advise against some inverts. Shrimp maybe a definite no.

My fish do this from time to time in a 500 gallon. My largest fish is a 5 to 6 inch Desarjini Sailfin. When I have introduced new fish I put up a mirror to direct their attention away from the newcomers. It makes the behavior much worse as the wrasses flash themselves in the mirror (which is absolutely stunning to watch), and the tangs tail flag each other. My tank is 4 side viewable, and they only do it on one end normally. I believe at least in my case they are catching reflections of themselves in the glass to initiate the behaviour.That's called "glass surfing". It can be a sign of stress. I can't tell you what the stressor might be though. To be honest, I don't have a lot of experience with this issue because all of my tanks are opaque on the back and sides. You could try draping the areas where the fish are doing with with black plastic.

Yea mine are only doing it on one side of the tank as well. Just weird to have never seen them do this until all this craziness has occurred.My fish do this from time to time in a 500 gallon.
