It delivers essential nutrients like chelated iron and potassium for rapid absorption, promoting strong, healthy, and vibrantly colored leaves while preventing yellowing and decay. Ideal for weekly use, it supports a thriving aquatic plant environment that complements water quality maintenance and fish health. ## Description The best way to keep your aquarium clean is to maintain good water quality. 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 & 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 & healthy. An aquarium is a closed environment and 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. The 5 common water quality parameters are Ammonia, Nitrite, Nitrate, and pH - all of which 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 & 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 β€˜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 (1) API LEAF ZONE Freshwater Aquarium Plant Fertilizer 473 ml Bottle - Promotes strong, hardy and colourful leaves and prevents yellow, decaying leaves - Contains essential nutrients including chelated iron and potassium - Formulated for rapid absorption in freshwater aquarium plants - Use for weekly monitoring and when water or fish problems appear ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0002566TW | | Best Sellers Rank | 4,064 in Pet Supplies (See Top 100 in Pet Supplies) 44 in Aquarium Water Treatments | | Brand Name | API | | Coverage | Freshwater planted aquariums | | Customer Reviews | 4.7 4.7 out of 5 stars (9,792) 4.7 out of 5 stars | | Global Trade Identification Number | 00317163105764 | | Item Form | Liquid | | Item Weight | 136 g | | Liquid Volume | 0.5 Litres | | Manufacturer | API | | Mixing Ratio | 5 ml per 10 US gallons | | Model Number | 576J | | Number Of Items | 1 | | Number Of Packs | 1 | | Part Number | 576J | | Specific Uses For Product | Aquarium | | Target Species | Aquatic Plants | | Unit Count | 473.0 millilitre | | Upc | 317163105764 019014705764 317163105672 | ## Product Details - **Brand:** API - **Item form:** Liquid - **Item weight:** 136 g - **Liquid volume:** 0.5 Litres - **Specific uses for product:** Plant Growth ## Images ![API Leaf Zone Plant Fertilizer for Freshwater Aquariums, 473 ml Bottle - Image 1](https://m.media-amazon.com/images/I/71WaB0EH-PL.jpg) ![API Leaf Zone Plant Fertilizer for Freshwater Aquariums, 473 ml Bottle - Image 2](https://m.media-amazon.com/images/I/818kAkDQtJL.jpg) ![API Leaf Zone Plant Fertilizer for Freshwater Aquariums, 473 ml Bottle - Image 3](https://m.media-amazon.com/images/I/91hkZDe4BTL.jpg) ![API Leaf Zone Plant Fertilizer for Freshwater Aquariums, 473 ml Bottle - Image 4](https://m.media-amazon.com/images/I/91O4Wa6gxaL.jpg) ![API Leaf Zone Plant Fertilizer for Freshwater Aquariums, 473 ml Bottle - Image 5](https://m.media-amazon.com/images/I/81mNITDh5HL.jpg) ## Available Options This product comes in different **Pattern Name, Style Name** options. ## Questions & Answers **Q: Can I use it for a goldfish tank ?** A: I think you can as it is for Aquarium plants just use the correct amount for the size of the tank.
