FAQ: What if I need to do a water change with tap water and use a dechlorinator like Seachem Prime® during the Cupramine™ treatment?

You will need to prepare the water 48 hours in advance of doing the water change. Add the Prime™ to your buckets of replacement water 2 days prior to doing your water change. The water will immediately be dechlorinated, and 48 hours later the Prime® will no longer be active and you can perform your water change safely. Remember, that you will also have to add Cupramine™ back to the replacement water to bring it up to the final concentration of the tank. This should be done just before doing the water change.
