API Pond Aqua Essential Water Conditioner
API Pond Aqua Essential is a highly concentrated all-in-one water conditioner that instantly makes tap water safe for fish by removing chlorine, chloramine, and detoxifying heavy metals commonly found in tap water.
It instantly removes toxic ammonia, nitrate, and nitrite levels in your pond. Toxic ammonia is released continuously by fish through their gills, urine, and solid waste. Uneaten food and decaying organic matter also contribute to ammonia buildup. Small amounts of ammonia can stress fish; large amounts can be fatal. This unique formula binds with ammonia, nitrite, and nitrate, rendering them non-toxic and allowing the biofilter to remove them more efficiently.
Usage
Use at pond start-up, whenever adding or changing water, or when water tests show elevated levels of toxins.
| Component | Function |

I’ve used this conditioner since setting up my pond last spring. It made the water safe right away after adding tap water. My fish haven’t shown any signs of stress since. Works well with my existing filter and has been reliable every time I change water.

Great product for new pond owners. I added it every time I changed water and noticed a big difference in fish behavior. The ammonia levels dropped quickly after use. Slightly more expensive than some alternatives, but effective.

Used during pond start-up and after water changes. My fish stayed healthy and active. The formula seems to neutralize toxins effectively and doesn’t leave any aftertaste in the water.
