Your All-in-One Concentrated Aquarium Water Conditioner
API® AQUA ESSENTIAL water conditioner is a highly concentrated all-in-one water conditioner that instantly makes tap water safe for fish by removing chlorine, chloramine and detoxifies heavy metals commonly found in tap water. AQUA ESSENTIAL water conditioner instantly removes toxic ammonia, nitrate and nitrite levels in freshwater, saltwater and planted aquariums. Toxic ammonia continually released by fish through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia. Small amounts of ammonia stress fish; large amounts of ammonia will kill fish. This unique formula binds with ammonia, nitrite, and nitrate rendering them non-toxic and allowing the water to be safe for aquatic life.

I’ve used AQUA ESSENTIAL for over a month in my 20-gallon freshwater tank. My fish have shown no signs of stress, and water tests show stable ammonia and nitrite levels. It’s easy to use and works quickly after adding it to the water.

Great product for new aquarium owners. It makes tap water safe right away. I added it before each water change and noticed my shrimp stayed healthy without any ammonia spikes.

My planted tank has been running smoothly since I started using AQUA ESSENTIAL. The water quality is much better, and my plants are thriving. No more fish deaths after water changes.
