API Aqua Essentials Treatment is a highly concentrated, all‑in‑one liquid water conditioner that helps create a safer, healthier environment for fish in freshwater, saltwater and planted aquariums. It works instantly to neutralise a range of harmful substances found in tap water and aquarium waste, making it an excellent first step in routine maintenance, tank start‑up, and after water changes.

Key Benefits:

• 💧 Makes tap water safe: Removes chlorine, chloramines and heavy metals often present in tap water, protecting fish from gill and tissue damage.

• 🛡️ Detoxifies toxic waste: Binds ammonia, nitrite and nitrate — toxic by‑products of fish waste and decay — rendering them non‑toxic and helping your biological filter remove them more efficiently.

• 🐠 Supports fish health: Reduces stress and risk of harm from water chemistry issues, particularly during tank set‑up, water changes or when test kits show elevated levels.

• 📆 Easy to use: Includes a dosing cap for simple measurement; add with water changes or as soon as issues are detected.

When to Use:

• At aquarium start‑up to condition new tap water.

• After routine water changes or top‑ups.

• When ammonia, nitrite or nitrate levels are elevated according to your test kit.

API Aqua Essentials combines multiple water‑treating actions into one bottle, giving you a comprehensive and convenient way to help keep water chemistry safe and balanced for your aquatic life.
