@AquaBiomics would know for sure, but I believe it wouldn’t be wise to submit a water sample until after all the copper is out of the water.

Yes, you should wait about a week after the copper treatment. As a general rule, you should wait about a week after any treatment to make sure the DNA of any dead parasites has cleared out. ~Melissa
Well I received my DNA results on my two tanks. My 225 that has my tangs sill has ich. Percent of eDNA is .167%.
My 560 (700 gallon system) had ZERO ich!!!! so H202 dosing eradicated the ich that was 96.4%, now the bad news it has something called Perkinsus. The link says it infects molluscs, but I have no molluscs so I'm lost on that one. Does anyone know if Perkinsus can infect fish?
Perkinsus is a genus of alveolates in the phylum Perkinsozoa. The genus was erected in 1978 to better treat its type species, Perkinsus marinus, known formerly as Dermocystidium marinum.[1] These are parasitic protozoans that infect molluscs, at least some of which cause disease and mass mortality. P. marinus is the most notorious, causing the disease perkinsosis, or dermo, in wild and farmed oysters.[2]

Do you feed clams?
Also it is not mentioned in Noga Book at all... So I would say that is pretty good sign it doesnt cause a lot of issues in marine fish.
I did feed the tank clams when I had the puffer and some triggers, but I haven't since they died in April. I also checked the tank and I did see a small vermetid snail (pulled that sucker out) and I did see a snail in the 80 that I forgot I put in there. Glad it should cause issues in fish!!

+1 Google Scholar only lists studies which discuss Perkinsus infecting bivalves.
ok thanks lol
Awesome I feel better about adding a couple fish that I QT or I get from a QT vendor.
Well I think I have no other choice than to break down the 560. After I let the tank sit with just the wrasse in it for about 8 months, and a clean Aquabiomics test. I added 4 fish and a clean up crew (Yellow Tang, Purple Tang, Bristletooth Tang and Powder Blue Tang) I purchased them from a fellow hobbyist in September who was getting out of the hobby. I placed them into two QT's, did HTTM and then still dosed peroxide all of October and November. The fish were healthy and no signs of any disease. I put them in the tank on December 9th. I noticed some ich on the Purple Tang a couple weeks later, so I set up the dosers with peroxide. I had been manually dosing previously on this tank. Today after about 3 weeks of dosing peroxide, the ich is killing the fish. (i can not get them out, i have tried they go into hiding in the rock work I have huge 50 pound pieces of rock). I have a call into my local fish store to see if he can come try to get them out with my help and put the remaining fish into his QT with copper. Yesterday they were all out swimming and eating today two are dead (powder blue and white tail bristletooth). So that is 3 fish left (Yellow Tang, Purple Tang and Coris Wrasse).
After the fish are out my plan is to drain the main tank, eel tank (eel had not been moved over yet fortunately) and the sump. I will remove all rock and as much sand as possible. Then refill with water and bleach and let that run for a few days dechlorinate it and then drain it again and let it sit empty for a bit while I get all new rock and sand. i will also bleach all the equipment in the tank.

Man you can’t catch a break
At least with this tank, my other tanks are doing well. Just kind of at a loss. I'll probably restart with mollies just to be safe this time, kicking myself for not going that route this time....i trusted the Aquabiomics test, but obviously it was still in the sand or rock crevices just waiting for me to put fish in.
Damn you were going through this when I was having problem last year. I'm sorry. What about hypo? I was dealing with a fluke issue I think but I ended up just nuking the tank with copper power. It worked. My Hermits are still alive. I still use the same rock and tank from it and haven't had any issues. Breaking down a tank that size after all you went through has to be heart breaking
Man alive!
So you did the EDNA Test and it came back 100% clean? Also where you dosing H2O2 when you got the clean results? I am starting to wonder if the H2O2 is messing with the test results.
