Okay. I have a pair of clowns and a small Valentini Puffer in a 10 gallon QT. They have gone through their two rounds of prazipro. I am getting ready to start copper. I have Seacham Cupermane. I know I need to get it to 2.o. I have the Hanna checker. Talk me through how to get my 10 gallon up to the 2.0 without doing harm! THANKS! I tried reading threads and doing the math and I am a little nervous to actually do it.
