Things You'll Need
- Activated charcoal filter
- Plastic container
- Hot water
- Salt water
- Copper test kit
Instructions
Remove the filter from the tank and replace it with an activated charcoal filter.
Take half of the water out of the tank and replace it with clean saltwater.
Remove anything from the tank that is not necessary, such as gravel, decorations and other items. Soak in hot water in a plastic container for one to two hours to remove traces of copper from the items.
Change 10 to 20 percent of the water one week later. Perform this same task in one additional week to remove traces of copper.
Test the water using a copper test kit to make sure that the copper has been removed completely.
