API Stress Coat is a liquid aquarium water conditioner formulated to remove chlorine, chloramines and neutralize heavy metals found in tap water. The formula contains aloe vera extract that helps replace the natural slime coat on fish that can be disrupted by handling, shipping, netting or fighting. It is intended for use whenever water is added or changed, when new fish are introduced, when setting up a new aquarium, or when fish show signs of skin or fin damage. The conditioner is dosed directly into aquarium water, with a standard dose used for routine conditioning and a doubled dose used to support slime coat repair and wound healing. It works instantly in the water column and is suitable for both freshwater and saltwater setups. The product comes in a liquid bottle format, with some sizes offered with a measuring pump for dosing convenience.
