*SeaChem Safe is a similar concentrated powdered version of Prime™ and is the complete and concentrated dry conditioner for both fresh and salt water. Safe™ removes chlorine, chloramine and ammonia as well perform all other aspects of water conditioning that Prime does (other than removal of some metals).
While Safe is a similar dry version of Prime, with the exception that it does not detoxify heavy metals, nor will it stimulate the natural slime coat of the fish. Unfortunately, due to its dry state, those benefits can not be achieved.
Safe cannot be made into Prime, as it does not have stabilizers like Prime and will not last long term in a liquid form. If diluted into a liquid, it must be used immediately. For these reasons, for the average aquarium keeper, AAPs founder recommends Prime over Safe.
*SeaChem Safe™ will not over-activate skimmers.
*Use at start-up and whenever adding or replacing water.
*Directions: Use 100 mg Safe (scoop) per each 100 L (25 gallons) as needed to reduce chlorine and chloramine or per 25 L (6 gallons) for ammonia. May be added to aquarium directly, but best if added to new water first.
