API AQUA ESSENTIAL water conditioner also removes toxic ammonia, nitrites, and nitrates to restore a healthy aquatic environment when your test results show high levels of ammonia, which is extremely toxic for fish.

Review: This works- happy, healthy fish - Excellent additive; use this each time I do a water change (add it to the pitcher I use to refill and pour it into the tank behind the filter media.) Have never had issues with my fish when using this, unlike some other additives I have used in the past. It is concentrated, so lasted about 3 months with weekly 10-25% water changes in a 20 gallon high tank.
Review: Fish haven't died.. Seems to do it's job - Fish haven't died.. Seems to do it's job. Doesn't have much of a smell, if any. My Ph levels haven't changed, but are at the right level to begin with. The water doesn't cloud, and is pristine.

## Features

- WORKS INSTANTLY: Highly concentrated aquarium treatment works instantly to remove harmful chemicals, making tap water safe for fish in freshwater, saltwater and planted aquariums; Reduces the risk of fish loss when starting or maintaining a fish tank
- DECHLORINATOR: Removes chlorine, chloramines, heavy metals which are found in tap water and can cause gill and tissue damage, breathing difficulty, stress and fish death
- AMMONIA REMOVER: Removes the 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

### ⭐⭐⭐⭐⭐ Fish haven't died.. Seems to do it's job
*by A***E on October 26, 2025*

Fish haven't died.. Seems to do it's job. Doesn't have much of a smell, if any. My Ph levels haven't changed, but are at the right level to begin with. The water doesn't cloud, and is pristine.

### ⭐⭐⭐⭐⭐ Clear the tank
*by R***M on September 2, 2025*

Works great but still takes a few days to clear up water to a crystal clear look. Priced rights and is fine in my 10 gal tank.
