So I never really had a qt tank or hospital tank. I have always just acclimated my fish to my tank and had pretty good luck. But like any other my luck has ran out and I lost almost all my fish to Brooklynella. I just bought a 50 gal that is separated into 3 completely isolated compartments to quarantine fish. Now my question is what copper treatment should I buy and how do I treat it? I have a sponge filter and heater in each compartment.
