I just tested the copper level that my QT tank is at, to see if the fish are ready to come out, and for over the 14day period it's been at 1.10ppm, and when I converted it to mg/L(how the medicine refers to the levels), its 1.1, which is almost twice the recommended dose, and still WAY over the apparent maximum safe dose on .8 mg/L! Can this be right? I have relatively sensitive fish in it, and they have all been happy and healthy the entire time--Bangaii cardinals, firefish, cleaner wrasse, green chromis(by the way, why are they so extremely delicate these days? They used to be crazy hardy!). I'm using cupramine, and the dose I'm going by is on the bottle, so Its definitely referring to the correct type of copper.
this is similar to before when I was treating my main tank after the oodinium or brooklynella event last year, and when I got the Hanna copper test kit, it turned out just following the directions put the level over 1.5, with angels, tangs, and a butterfly, which I can't imagine would have all survived if the level was truly twice the maximum safe level.
Whats the deal here, there's gotta be some mistake somewhere. Are the numbers and dose info all correct and my fish are just all from krypton, or are the number/dose info off, and im not treating with a high enough dose?
