Nice. Now lets hope that it is the solution to the problem, I think the area of diseases and parasites and then the medications/treaments is the most difficult part of keeping fish.
That looks like a lot of white powder, lol. I hope it helps your fish Joel. I often keep extra meds in the fridge or freezer if my chemist husband thinks I should. He judges by the chemical composition & his experience rather than a random expiration date...there's a squish factor too...but no guarantees either...Good luck!
I just came across a post on MFK which asked about the proper amount of metronidazole to put into feed for a sting-ray. While I have made metro food, I was never precise re the dose. So I was searching for info to offer a decent answer. What I found made me do a double-take. it would explain a lot of the problem in finding the med FF needed.
If you go to the link below it will take you to what appears to be the site for the FDA (United Syates Food and Drug Administration). It is a warning letter dated Oct. 6, 2020 issued to a site called Everything Aquatiq dealing with the medications the site was offering. Ot is a longish list and includes some of the drugs many of us have used for years. This includes metro as well as a host of others drugs.

I have SeaChem Metro pwowder in my neds kit, but checking the SeaChem site you cannot find it any more. However, they do sell Metroplex which contains Metro.
