Venting?

[Brisbane Lion]

Hi everybody....I'm not sure you can help me and I fear this may become something of a venting exercise for me. I will try to be brief. I have been keeping marine fish for over 40 years. It took me about 10 years to stop trying shortcuts and do the right thing. About 20 years ago I had a case of whitespot disease which wiped out all my fish. Ever since all my fish have gone through a strict quarantine in a quarantine tank of course and I have not lost a fish to anything for the last 10 years. This brings me to my problem. I recently purchased 6 cardinal fish and a flame angel. After 6 weeks in cupramine I realeased them into my display tank. After about 2 months what appeared to be white spot spot appeared and wiped out all my fish in less than 2 weeks. Out of desperation and as my tank is FOWLR i dosed my DT with cupramine but to no avail i'm afraid. Please how is this possible or else just help.

I assume you had velvet that was not killed off in the cupramine and just masked it. How did you check the concentration of the cupramine? Copper products aren’t great for treating velvet since it has been shown that velvet can withstand the concentration level of copper that’s lethal for fish but didn’t kill velvet. Chloroquine phosphate is the better choice for velvet if your fish can handle CP.

Chloroquine phosphate

Chloroquine phosphate

Does this have a commercial name?

What test kit do you use to ensure that Cupramine is at a therapeutic level (0.5 mg/L) at all times? It is especially needed when dosing in a DT environment because rock will absorb most of the copper initially.

Yeah, copper isn't a good treatment for Velvet.
CP is the way to go. But for CP to be for sure effective it should be used in a sterile treatment tank.
