About this item
Product details
Treat your tap water, and provide a safe environment for freshwater fish instantly and easily with API STRESS COAT Freshwater Aquarium Water Conditioner. Tap water contains chlorine, chloramines and ammonia which can cause gill and tissue damage, breathing difficulty, stress and death. API STRESS COAT Aquarium Water Conditioner works instantly as a water conditioner to remove chlorine and chloramines from tap water and neutralize heavy metals. API STRESS COAT Freshwater Aquarium Water Conditioner Treatment contains aloe vera to protect the fish's skin. Proven to reduce fish stress, which can result from changing water, poor water quality and handling fish. This conditioner replaces the natural secretion of slime that is interrupted by handling, shipping, fish fighting, or other forms of stress and helps heal torn fins and skin wounds while promoting tissue regeneration. API STRESS COAT is recommended by professional fish handlers. With API aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

Treats aquarium water and reduces stress on fish
I have used this product for many years and trust it to treat my aquarium water to make tap water safe for my tropical fish, and also to reduce stress on my fish when changing water. It works and I recommend it to everyone with an aquarium.
