At this point I am watching very closely for external symptoms of bacterial infections. If one arises or a fish prone to infection stops eating then I dose Spectogram (Kanamycin+Nitrofurazone) and continue throughout copper. You can also use Kanaplex+furan-2. The WCs are fun maintaining the therapeutic Cu level. But once you have the hang of it, it's not bad. Copper has to be pre-dosed into new SW prior to adding to tank to keep Cu level from dropping below therapeutic.
when using copper power and kannaplex +furan 2. Since Furan 2 will change the tank water to yellow Tint. Will you still get an accurate reading on the Hanna checker?
thanks
