Hi,

I have 4 fish in a 55 gal QT - 2 female Bellus Angels, a Flame Hawk, and a very small Kleini butterfly. They have all developed either ick or velvet (I think velvet based on speed of onset, which was less than 24 hours, and too many spots to even count). I started cupramine and raised it to 0.5 ppm. This was on 3/9.

All seems ok but one Bellus hasn't eaten. (She was eating well previously). I was doing some reading last night and found these 2 threads, which indicate that cupramine can be slightly lower than I've been targeting. After a water change last night my final QT reading was 0.43 - which is strange because the QT tested at 0.52 prior to the water change and the new water at 0.50. But whatever. Based on these threads I left it alone. Today, the angel ate for the first time since starting cupramine.

So, is safe/effective to leave my cupramine level slightly lower, if it means the Bellus will eat? The threads I am referencing are a little old. I've tried just about every food, including live brine and live blackworms. The food she ate tonight was a mix made for angelfish and butterflies that she previously wouldn't eat.

TIA,

Cindy


 
For years, Seachem was quoted as saying that the therapeutic range of Cupramine minimum at 0.35 but to shoot for 0.50. That was before we had the Hanna HL Copper Checker, and the color matching test kit from Seachem was just awful in the lower range to judge. Also the Hanna's accuracy is + or - 0.05. I'm sure you are fine. Just remember to observe the fish after the copper has been removed for 10-14 days or so.

Thank you. They'll be moving to a new tank after 14 days of copper. I'm hopeful that they will make it :)
