NTL Spare Phosphate PO₄ Test Kit Reagent NTL Spare Phosphate PO₄ is a replacement reagent designed for testing phosphate levels in aquarium water. Phosphate is an essential nutrient in aquatic systems, but excessive levels can contribute to unwanted algae growth and negatively affect aquarium balance. Regular phosphate testing helps aquarists identify rising phosphate levels and maintain better water quality for fish, plants, and aquatic environments. Key Features Replacement reagent for phosphate (PO₄) testing. Helps monitor phosphate levels in aquarium water. Supports routine aquarium water quality management. Helps identify conditions that may encourage algae growth. Suitable for freshwater aquarium testing. Benefits Helps maintain balanced aquarium water conditions. Allows early detection of rising phosphate levels. Supports algae prevention by monitoring excess nutrients. Helps improve aquarium maintenance routines. Ensures continued use of your existing NTL phosphate test kit. Understanding Phosphate (PO₄) Phosphate is naturally introduced into aquariums through: Fish food. Fish waste. Breakdown of uneaten food and organic matter. Tap water used during water changes. While phosphate is required in small amounts for biological processes and plant growth, elevated levels can contribute to nuisance algae growth and should be monitored regularly. Recommended Phosphate Levels Phosphate should be kept as low as practical while still supporting healthy aquarium life. Planted aquariums may require some phosphate availability for plant growth. Regular testing helps identify unwanted increases before they become a problem. What to Do if Phosphate Levels Are High Perform regular partial water changes using suitable water. Test tap water to check whether phosphate is being introduced during water changes. Reduce excess organic waste by maintaining good filtration and aquarium cleanliness. Consider phosphate-removing products if required. How to Use Ensure the test tube is clean. Add the required aquarium water sample to the test tube. Add phosphate reagent according to the instructions supplied with your NTL phosphate test kit. Mix gently and allow the test to develop. Compare the colour of the sample with the supplied colour chart to determine phosphate levels. Specifications Product: NTL Spare Phosphate PO₄ Reagent Application: Replacement reagent for phosphate water testing. Suitable For: Aquarium water testing. Test Type: Liquid reagent colour comparison test. Why Choose NTL Spare Phosphate PO₄? Keeping phosphate levels under control is an important part of aquarium maintenance. NTL Spare Phosphate PO₄ makes it easy to continue monitoring this important water parameter, helping you maintain a cleaner aquarium and reduce the risk of unwanted algae problems.

NTL Spare GH (General Hardness) Test Kit Reagent NTL Spare GH is a replacement reagent for testing the General Hardness (GH) of aquarium water. GH measures the total concentration of dissolved minerals, such as calcium and magnesium, which play an important role in the health of aquarium fish and plants. Knowing your aquarium's GH helps ensure you maintain water conditions suited to the species you keep. Regular GH testing is an essential part of maintaining a stable and healthy freshwater aquarium. Key Features Replacement reagent for GH (General Hardness) water testing. Measures dissolved mineral levels in aquarium water. Suitable for freshwater aquarium monitoring. Simple drop-count test with an easy colour change. Helps maintain ideal water conditions for different fish species. Benefits Allows accurate monitoring of aquarium water hardness. Helps create the correct environment for soft or hard water fish. Supports fish health by maintaining stable water chemistry. Easy-to-read results using a colour change method. Ideal for routine aquarium maintenance. Understanding GH General Hardness (GH) measures the total amount of dissolved minerals in the water. The more minerals present, the harder the water. Different fish species require different GH levels: Soft water species: Approximately 3–6 dGH Hard water species: Approximately 10–15 dGH One degree of GH (1 dGH) is equal to 17.8 ppm (as CaCO₃). What to Do if GH is Incorrect Test your tap water to determine its natural GH. If GH is too high, consider using reverse osmosis (RO) water to reduce hardness. If GH is too low, calcium carbonate-based rocks, such as ocean rock, can help gradually increase mineral hardness. How to Use Ensure the test tube is clean. Fill the test tube with 5ml of aquarium water. Add 2 drops of GH A reagent and mix. The sample should turn dark pink. Add GH B reagent one drop at a time, mixing between each drop. Count the number of drops required for the sample to change from pink to blue. The number of drops used equals the GH value in dGH. If the first drop of GH B turns the sample blue, the GH is below 1 dGH, indicating very soft water. Specifications Product: NTL Spare GH Reagent Application: Replacement reagent for General Hardness (GH) water testing. Suitable For: Freshwater aquariums. Measurement Range: Results expressed in dGH (degrees of General Hardness). Test Method: Liquid drop-count colour change test. Why Choose NTL Spare GH? Maintaining the correct General Hardness is essential for the long-term health of your aquarium's inhabitants. NTL Spare GH replacement reagent makes it easy to monitor mineral levels accurately, helping you provide the ideal water conditions for your fish and maintain a stable aquatic environment.

NTL Spare Ammonia (NH₃) Test Kit Reagent 10ml NTL Spare Ammonia (NH₃) is a replacement reagent for testing ammonia levels in aquarium water. Ammonia is the primary waste product produced by fish and can also result from uneaten food and decaying organic matter. Although invisible, ammonia is highly toxic to aquarium fish, making regular testing essential for maintaining a healthy aquatic environment. Use this reagent to accurately monitor ammonia levels and take action before they become harmful to your fish. Key Features Replacement reagent for ammonia (NH₃) water testing. Helps monitor one of the most important aquarium water parameters. Detects harmful ammonia levels before they become dangerous. Suitable for routine freshwater and marine aquarium water testing. Easy-to-use drop test method. Benefits Helps protect fish from harmful ammonia exposure. Supports a healthy and stable aquarium environment. Assists in identifying water quality issues early. Encourages effective aquarium maintenance and filtration management. Simple colour comparison for quick, reliable results. Understanding Ammonia Ammonia is produced naturally through: Fish waste. Uneaten fish food. Decaying plants and organic matter. Beneficial bacteria in your biological filter convert ammonia into the less toxic compound nitrite. However, any detectable ammonia is considered unsafe. Recommended ammonia level: 0 mg/L (ppm) at all times. What to Do if Ammonia is Detected 0.2 mg/L (ppm): Add a filter booster such as Filter Starter. 0.5–1.0 mg/L (ppm): Perform a 25% water change. Above 1.0 mg/L (ppm): Perform a 50% water change. Use an ammonia-removing filter media where appropriate. If ammonia is present, also check other key water parameters including pH, KH, and nitrite. How to Use Ensure the test tube is clean. Fill the test tube with 5ml of aquarium water. Add 5 drops of Ammonia 1 and 5 drops of Ammonia 2 reagent. Replace the cap and shake thoroughly. Wait 10 minutes. Compare the sample colour to the supplied colour chart with the test tube against the white reference area. A yellow colour indicates 0 mg/L (ppm) ammonia. Any green tint indicates the presence of ammonia. Specifications Product: NTL Spare Ammonia (NH₃) Reagent Application: Replacement reagent for ammonia water testing. Suitable For: Freshwater and marine aquariums. Test Method: Liquid drop test with colour comparison.
