About the Seachem Aquarium Water Treatment - 500 ml / 17 fl. oz
Seachem Aquarium Water Treatment for Freshwater and Saltwater
Seachem is a concentrated aquarium water conditioner designed for both freshwater and saltwater fish tanks. This 500 ml (17 fl. oz) treatment effectively removes chlorine and chloramine, ensuring a safe environment for your aquatic pets.
This powerful treatment detoxifies ammonia, nitrite, and heavy metals commonly found in tap water, creating an ideal habitat for fish such as bettas and tetras. Seachem is formulated to work immediately, allowing beneficial bacteria in your biofilter to manage harmful substances effectively. For optimal results, add Seachem to new water before filling your tank. In cases of high chloramine concentrations, a double dose can be safely administered. For smaller volumes, simply use 2 drops per gallon.
