Treat your tap water and provide a safe environment for freshwater fish easily with API Aqua Essential water conditioner. Tap water contains chlorine, chloramines and ammonia which can cause gill and tissue damage, breathing difficulty, stress and death. API Aqua Essential Tap Water Conditioner works instantly as a water conditioner to remove chlorine and chloramines from tap water and neutralize heavy metals. Ammonia is continually released by fish through their gills, urine, solid waste, uneaten food and decaying organic matter; small amounts of ammonia stress fish, large amounts of ammonia will kill fish. Additionally, nitrites inhibit respiration and suppress the immune system at low levels, while high levels cause suffocation whilst nitrates can be harmful to fish and lead to algae growth. The API Aqua Essential Tap Water Conditioner removes toxic ammonia, nitrites, and nitrates to restore a healthy aquatic environment. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot.
