I'm doing an introduction 2month copper treatment after finally adding my new angels, but I want to be 100% sure it's effective enough--what are the ideal copper levels? I'm using cupramine. I remember there's a "standard" medication level, and i was told that some people double it, which I did after the oodinium or brooklynella murders, but I can't remember now(it's been the better part of a year, i think...maybe around 9+ months?). I think ideal/double was 50/100, but I don't want to end up having done 2 months of innefective treatment, and still be at serious risk.
I got the API, and seachem copper tests, which are always off from each other by about .50ppm I believe, so I'm never 100% sure where I'm ever actually at, so I try to keep in mind I could be anywhere within that range. Of course I'm never totally sure anyway, cause the API instructions don't say if ur supposed to use the color visible while holding the vial in the air above the card(I believe that's correct), or against the card, which makes a significant difference(maybe from shadow/no shadow?), and the seachem test assumes you can eyeball the result from along a fading color scale where probably only a computer could differenciate anything within .50ppm!
