Frequently Asked Questions (FAQs)

1. How long do you treat fish with copper?

For every 10.5 gallons of water, use 1 mL of treatment, and then wait 48 hours. Repeat the treatment, and leave at this concentration for 14 days. Test the water for copper levels before redosing the tank.

2. How do I add copper to my aquarium?

Once you have determined that you will treat your freshwater aquarium with copper ions, the first thing to do is to get it. Some people add copper containing coins or even copper wire to the tank in the hopes that this will release a small amount of copper ions into the tank.

3. How much copper is too much for fish?

The most toxic form of copper is the cupric ion (Cu2+). Fish and crustacea are 10 to 100 times more sensitive to the toxicity of copper than mammals. For salmonids, the upper recommended limit is < 0.03 mg/l in hard water (>100 mg/l CaCO3) while in soft water it is <0.0006 mg/l.
