First, what copper test do you have?@Jay Hemdal can you walk me through how i do a copper power treatment? just what ppm to start with and after how many days do i up the ppm and stuff like that?
What you do is figure the actual water volume of the tank. Then calculate what a half dose of copper power would be and add that. Let that circulate for a few hours and test - you should be at 1.25 ppm or close to it. Then, you dose proportionally more to get to 2.5 ppm. Then test every few days to hold it between 2 and 2.5 ppm for 30 days.
