Product Information

API Stress Coat Marine 473 ml – Marine water conditioner with Aloe Vera that instantly removes chlorine, chloramines, and heavy metals while helping reduce fish stress, support natural slime coat protection, and aid recovery after transport, acclimation, water changes, and handling. Suitable for saltwater and marine aquariums.

Marine fish experience stress from many common aquarium events including transportation, acclimation, water changes, tank transfers, netting, aggression, and environmental changes.

API Stress Coat Marine is a premium saltwater water conditioner specifically formulated to make tap water safe while helping support the fish’s natural protective slime coat.

Unlike standard dechlorinators that only remove chlorine and chloramines, API Stress Coat Marine also contains Aloe Vera, which helps protect and support the regeneration of the fish’s natural slime coat—its first line of defense against stress and environmental challenges.

Whether you’re setting up a new marine aquarium, performing a routine water change, introducing new fish, or helping fish recover from handling stress, API Stress Coat Marine is an essential part of marine aquarium maintenance.

Instantly Conditions Tap Water

Tap water can contain chlorine, chloramines, ammonia, and heavy metals that may be harmful to marine life. API Marine Stress Coat works quickly to neutralize these contaminants, creating a safer environment for fish and other aquarium inhabitants.

Promotes Healthy Skin and Fins

Enriched with aloe vera, this unique marine conditioner helps support the natural healing process of fish while promoting healthy skin and fin tissue. It is especially beneficial during water changes, fish handling, transportation, and aquarium maintenance.

Helps Reduce Fish Stress

Sudden water changes and environmental fluctuations can place stress on marine fish. API Marine Stress Coat helps minimize stress while supporting a healthier and more comfortable aquatic environment.

Safe for Reef Aquariums

This formula is safe for use with corals, reef systems, and marine invertebrates, making it suitable for a wide variety of saltwater aquarium setups.

Compatible with Protein Skimmers

Unlike many traditional water conditioners, API Marine Stress Coat is specially formulated for saltwater aquariums and will not cause excessive foaming in protein skimmers, ensuring uninterrupted filtration performance.

Supports Long-Term Aquarium Health

By neutralizing harmful substances and protecting fish during stressful situations, this conditioner contributes to a healthier, more stable marine aquarium environment.
