I decided to use Copper Power to treat my fish. I started dosing on July 23rd and my current reading it 1.0ppm of copper power. As of tonight Im not seeing any changes in behavior or eating. Im shooting for 1.75-2.00ppm for my Therapeutic Level per the following thread https://www.reef2reef.com/threads/ratios-for-dosing-copper-power.385871/ Ive also calculated for every 5ml of Copper Power I add I see an increase of 0.12ppm. My DT has to be fallow until Oct 6 2018 or later.
