This will keep your fish strong and vibrant, as well as preventing disease. It is important to test your aquarium water weekly to verify good quality in addition to a bi-weekly partial water change of no more than 25% to help reduce toxic buildup, remove debris the filter missed, and replenish the oxygen available to fish. Feed your fish twice daily only the amount of food they can eat in 2 to 3 minutes depending on the species. Some fish such as bottom feeders and algae eaters will need up to 30 minutes to 2 hours. Overfeeding and low quality nutrition cause unconsumed food and more excrement which cloud water and raise harmful ammonia levels, possibly leading to fish loss. Take time to observe fish and the water temperature to ensure they are active and healthy. In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly with API MASTER TEST KITS or API 5-IN-1 TEST STRIPS. It is also a good time to add API STRESS ZYME to keep your aquarium and gravel clean. In a closed aquarium environment there are no natural rivers or streams to carry away debris and other waste materials. It is important to renew 25% of the aquarium water every two weeks. When you change the water, it is important to know that tap water contains chemicals that make it safe for us to drink but harmful for fish, therefore add a water conditioner such as API STRESS COAT. It is important to change your filter media & clean gravel monthly, however in doing so it can disrupt the fragile ecosystem of your aquarium. Use API QUICK START to strengthen it with ‘beneficial’ nitrifying bacteria that will naturally consume toxic compounds and help prevent fish stress. Also recommended when starting a new aquarium or changing the water. ## Features - Contains one Api stress coat aquarium water conditioner 19 liter Bottle - Makes tap water safe and protects fish with dual-action formula - Removes chemicals from tap water that are harmful to fish - Replaces fish’s protective coat damaged by handling, shipping or fish fighting with healing power of Aloe Vera extract - Use when adding or changing water, when adding a fish and when fish are sick or injured ## Technical Specifications | Specification | Value | |---------------|-------| | Allergen Information | Apple Free | | Asin | B000256DIG | | Best Sellers Rank | 844 in Pet Supplies (See Top 100 in Pet Supplies) 4 in Aquarium Water Treatments | | Brand Name | API | | Country Of Origin | USA | | Customer Reviews | 4.8 4.8 out of 5 stars (35,487) 4.8 out of 5 stars | | Global Trade Identification Number | 00317163111857 | | Included Components | API STRESS COAT Aquarium Water Conditioner 64-Ounce Bottle | | Item Form | Liquid | | Item Type Name | API STRESS COAT Aquarium Water Conditioner 64-Ounce Bottle | | Item Weight | 1 Pounds | | Liquid Volume | 64 Fluid Ounces | | Manufacturer | API | | Manufacturer Part Number | 85J | | Model Number | 85J | | Number Of Items | 1 | | Number Of Packs | 1 | | Pet Type | Fish | | Target Species | Fish | | Unit Count | 1900.0 millilitre | | Upc | 716184521049 317163111857 | ## Product Details - **Brand:** API - **Item form:** Liquid - **Item weight:** 4.9 Pounds - **Liquid volume:** 64 Fluid Ounces - **Number of Packs:** 1 ## Images ![API Stress Coat Aquarium Water Conditioner, 1.9 Litre Bottle - Image 1](https://m.media-amazon.com/images/I/61vP7ekME5L.jpg) ![API Stress Coat Aquarium Water Conditioner, 1.9 Litre Bottle - Image 2](https://m.media-amazon.com/images/I/61TDaOQENcL.jpg) ![API Stress Coat Aquarium Water Conditioner, 1.9 Litre Bottle - Image 3](https://m.media-amazon.com/images/I/A1XKpmOC3NL.jpg) ![API Stress Coat Aquarium Water Conditioner, 1.9 Litre Bottle - Image 4](https://m.media-amazon.com/images/I/81Noeku1i9L.jpg) ![API Stress Coat Aquarium Water Conditioner, 1.9 Litre Bottle - Image 5](https://m.media-amazon.com/images/I/81XbpqXcmdL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Useful aquarium water conditioner. *by on Reviewed in the United Kingdom 31 July 2026* I am pleased with my purchase as it seems to be working very well.
