Before you can put fish and plants in a pond you need to make sure the water is safe for aquatic life. Municipal water treatment systems add chlorine and chloramine to the water we drink to make it safe for human consumption. However, those same chemicals are not safe for fish and plants.
After a new pond gets filled or an existing pond gets cleaned out and new water added chlorine and chloramine needs to be removed. A “dechlorinator” like SuperNaural PondPrep will remove those chemicals so you can add your fish and plants quickly.
Don’t forget to Prep! You’ll be happy you did.
