Instructions
Change the filter in the tank. You need a filter that uses activated charcoal to effectively remove the copper from the water. If you already use an activated charcoal filter, change the charcoal when you hook the filter back up after the carbon treatment.
Do a 50 percent water change on your tank. This will help to minimize the amount of copper that is in the water once you refill the tank.
Clean all of the decorations in the tank that can be removed. Rinse the decorations in hot water. Don̵7;t use any chemicals when cleaning the decorations.
Wipe down the interior of the acrylic tank using a no-scratch aquarium scrubber. Copper may attach to small particles or small nicks in the interior surface of an acrylic fish tank.
Do a 10 to 20 percent water change and clean the interior of the tank one week after the previous water change. Once you do this, the tank should be copper-free.
Test the water using a copper test kit for saltwater aquariums. These kits are usually available at pet stores that sell saltwater products. If there isn̵7;t any copper in the aquarium, it is safe to add sensitive fish or invertebrates as long as the other tank factors, such as salinity and ammonium, are at appropriate levels.
How to Remove Copper From an Acrylic Saltwater Aquarium
Copper is used in saltwater fish tanks to treat certain illnesses, such as ich. However, copper is unsafe for reef tanks that contain invertebrates, so removing this chemical before adding any invertebrates is vital to ensuring they can survive in the aquarium. Removing copper from an acrylic tank is almost the same as removing it from a glass tank.
