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 ‘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 PHOSPHATE TEST KIT 150-Test Freshwater and Saltwater Aquarium Water Test Kit, including two bottles of testing solution, two colour cards and one glass test tube with cap - Reads phosphate levels between 0-10 mg/Litre - Helps monitor and adjust pH and prevent invisible water problems that can be harmful to fish and corals - Reducing phosphate can help prevent excess and unsightly algae, which can cause fish stress and inhibit the growth of hard corals - Use for weekly monitoring and when water or fish problems appear ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00BUFRY30 | | Batteries Included | No | | Batteries Required | No | | Best Sellers Rank | 17,100 in Pet Supplies (See Top 100 in Pet Supplies) 32 in Aquarium Test Kits | | Colour | No Color | | Customer Reviews | 4.4 4.4 out of 5 stars (238) 4.4 out of 5 stars | | Date First Available | 13 May 2016 | | Delivery Information | We cannot deliver certain products outside mainland UK ( Details).

Ofcourse only got this to test the water so nothing to compare. It comes with a very handy plastic 5ml test tube that got a lid that is attached. Prefer using this one. ### ⭐⭐⭐⭐⭐ Easy to use test kit *by on Reviewed in the United Kingdom 31 May 2020* Use api test kits all the time easy to read results. Used on both my marine and freshwater tanks with no problems. ### ⭐⭐⭐⭐ API phosphate tester *by on Reviewed in the United Kingdom 27 February 2023* Good value when you consider the number of tests you can carry out. However, not great if you need to be super accurate in the lower end of the phosphate scale as may do with saltwater tanks. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/53484783-api-phosphate-test-kit-for-freshwater-and-saltwater-aquariums-150](https://www.desertcart.com.br/products/53484783-api-phosphate-test-kit-for-freshwater-and-saltwater-aquariums-150) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-29*
