If you read the patent you'd understand the chlorine produced in the water is removed after going through the electrocoagulation process. NaCl - Cl. That's why there's an approved patent that claims to raise fish in a CHEMICAL FREE ENVIRONMENT because indeed they ARE. Recirculating means just that, water cleaned, recycled, in a closed system. The fish aren't SWIMMING in water that has chlorine in it. Ever.
Instead of sending out non founded information to try to get people to sell why dont you verify the information first. Oh that's right you have come to discredit.. bahahaha
