I will be using my 72 gal bowfront tank that I had used as a freshwater tank for my saltwater tank along with the emperor power filter with biowheels. I had used copper in my freshwater tank. I am worried after reading how copper kills invertebrates in SW tanks. I have cleaned the tank with water and washed out the power filter and biowheels. I am going to run some coppersorb through the power filter and tank when I cycle my tank with live rock. The question is-- Is this enough to allow me to keep some invertebrates in my reef tank? Thanks.
