A natural pond has a constant supply of fresh water flowing into it, such as from a stream or spring. Water also flows out of a natural pond, taking fish waste and other toxins with it. This isn’t true for most garden ponds as they are closed systems. Garden ponds also tend to be much smaller than natural ponds, so they do not offer the amount of water per fish that you find in nature. For these reasons, water treatments are necessary to keep water conditions safe for both fish and plant life and for clearer water. Following specific steps each season allows you to create a backyard retreat you’ll enjoy all year long! For more information about what’s needed each season, check out more below. Spring Start Up - Get Your Pond Ready! Its pond startup time! Whether filling a new pond or re-establishing an existing pond, following some simple steps at startup will yield benefits you’ll enjoy all season long. The 3 key steps that must be taken are making your tap water safe, activating the natural pond cycle, and maintaining sparkling clean water to boost fish and plant health. Once the water temperature reaches above 10⁰C, you’ll also want to start feeding your fish again. It is important to take care of all of your plants in the spring with API AQUATIC PLANT MEDIA and API AQUATIC PLANT FOOD TABLETS as they will be the key to success in most ponds! Lastly, monitor the water conditions in your pond with the API POND MASTER TEST KIT, an easy and accurate way to test 4 key water parameters including pH, ammonia, nitrite, and phosphat Summer - Provide Regular Care And Enjoy Your Pond Summer is the time to sit back and enjoy all of your hard work! You’ll need to continue regular care for your pond that includes adding beneficial bacteria like API POND-ZYME and API POND ECOFIX. While everything looks great, you’ll want to closely monitor the water conditions so that you can protect the health of your pond including plants and fish. Algae grows in the presence of sunlight where there is excess nutrients in the pond water for the algae to feed on. API POND ALGAE CURE has been used for over 18 years to effectively control green water algae, string algae, and blanketweed without harming fish or plants. At this time it could be beneficial to do a partial water change, adding API POND STRESS COAT and API POND SALT and fertilizing your pond plants Autumn - Prepare For Winter Performing a few simple steps in the autumn will prepare your fish and plants for the long, cold winter ahead and lay the foundation for a healthy start in the spring. We recommend removing excess organic matter to reduce fish stress during the winter months. Use a net to remove as many leaves as possible. Routine addition of API POND ECOFIX or API POND-ZYME throughout the season promotes healthy water quality and reduces the amount of organic matter you need to remove at the end of the season. It is also important to perform a 25% water change, adding API POND STRESS COAT and API POND SALT to make the tap water safe and to replenish important electrolytes which aid fish during the stressful winter months. Winter – Keep Pond Water Circulating In cooler climates, when the water temperature drops, fish will naturally eat less than at warmer temperatures. Once the water temperature drops below 5⁰C, fish will stop eating and if they have been fed properly through the summer and autumn, they will have ample reserves to survive the rigours of winter. It is also important to ensure your pond has circulation to keep an open area on the ponds surface throughout the winter months to prevent the buildup of toxic gases which can accumulate from the decomposition of organic matter.

Review: Great for houseplants too! - I have been adding this to my watering can every time I water my house plants for a few months now and I have noticed that my sulky peace lily has fewer and fewer brown and yellow edges to it’s leaves. I have had this plant for years and the new growth is lush and green. I have noticed that new plants watered with this in the water have not had any discoloured leaves, so as far as I am concerned it is working well for my purposes. Review: I would purchase again. - Worth every penny. ## Features - Contains one (1) API STRESS COAT Aquarium Water Conditioner 237 ml 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 new fish and when fish are sick or injured ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002567CI | | Allergen Information | Apple Free | | Best Sellers Rank | 1,000 in Pet Supplies ( See Top 100 in Pet Supplies ) 5 in Health Supplies for Fish & Aquatic Pets | | Brand | API | | Brand Name | API | | Customer Reviews | 4.8 out of 5 stars 34,909 Reviews | | Global Trade Identification Number | 00317163080856 | | Item Form | Liquid | | Item Type Name | Aquarium Water Conditioner | | Item Weight | 0.4 Pounds | | Item form | Liquid | | Item weight | 0.4 Pounds | | Liquid Volume | 118 Millilitres | | Liquid volume | 118 Millilitres | | Manufacturer | API | | Manufacturer Part Number | 85A | | Model Number | 85A | | Number of Packs | 1 | | Pet Type | Fish | | Target Species | Fish | | UPC | 317163080856 | | Unit Count | 237.0 millilitre | | Unit count | 237.0 millilitre | ## Product Details - **Brand:** API - **Item form:** Liquid - **Item weight:** 0.4 Pounds - **Liquid volume:** 118 Millilitres - **Number of Packs:** 1 ## Images ![API Stress Coat Aquarium Water Conditioner, 237 ml Bottle - Image 1](https://m.media-amazon.com/images/I/51KQtbsDfFL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: How much to use for 200l?** A: Not sure, however I seem to remember it worked out at 20ml for 100l so that would make it 40ml. It tells you on the label I'm sure **Q: Can one use api stress coat with purigen?** A: Yes, I use purigen bags in my canister and use stress coat when doing water changes **Q: Where it says "5ml per 40L of water" does it mean per 40L putting in a per 40L that's already in the tank? How much should I put in a 10L bucket?** A: ******20 drops for 10litre******to remove chlorine and chloramines...#### To replace slime coat and repair damaged tissue 10ml per 40litre of water###...So on a water exchange use *******when tank is full use #### I do hope that makes sense. But the instructions are clear on the Bottle.It is an excellent product. Good Luck. **Q: How long do have to leave the makeup water in a bucket before I can use it.** A: Hi. You can use treated water straight away. I get freshwater ready first then empty out old tank water then put in the new treated water back into the tank. No harm is done to your fish i have always done it this way. And all my fish are healthy n happy swimming around. Hope this helps. 🐟🐠😄 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for houseplants too! *by D***A on 28 May 2026* I have been adding this to my watering can every time I water my house plants for a few months now and I have noticed that my sulky peace lily has fewer and fewer brown and yellow edges to it’s leaves.
