DO NOT use a full dose of eco-balance or waste-away on the same day as using  First Defense

Changing the environment of a fish causes stress that robs fish of essential nutrients and can weaken their immune system. First Defense is scientifically designed to provide stress relief and support the immune system, helping fish cope with stress due to bagging and shipping from the store to your tank, water changes, new fish additions, disease treatments, and other environmental changes.
