## Description

NT Labs Marine Lab Phosphate Test Kit, Marine Aquarium Water Testing Kit, Accurate Results, Contains up to 40 Tests.

## Features

- 【 MONITORS PHOSPHATE LEVELS IN MARINE AQUARIUMS】: Phosphate is an essential component in fish nutrition, but is also produced as a waste product by fish. Phosphate is practically non-toxic to fish, but excess phosphate can cause unwanted algae and will inhibit coral growth. Maintaining a low level of phosphate is essential for reducing unwanted algae and maintaining coral growth rates. Phosphate tends to accumulate as an aquarium ages, so regular monitoring of phosphate is required to determine the health of the aquarium.
- 【 EASY TO USE】: Using the syringe provided, add approximately 5 ml of water to the glass test tube. Cap the test tube and shake briefly to wash the test tube. Uncap the test tube and discard this water. Add 10 ml (2 x 5 ml using the syringe) to the test tube. 3. Add 10 drops of Phosphate-1 Reagent. Add 10 drops of Phosphate-2 Reagent. Cap the test tube and shake well to mix. Wait for 5 minutes for the colour to develop. Once the 5 minutes has elapsed, uncap the test tube. View from the top and compare to the colour chart to determine the amount of phosphate present in the water.
- 【 HOW TO FIX PHOSPHATE ISSUES 】: Phosphate in natural seawater generally varies from 0.01 mg/l to 0.06 mg/l (in terms of phosphorus) in reef areas. However, in a reef aquarium, aim for 0.03 mg/l to maintain good coral growth and keep nuisance algae at to a minimum. Regular maintenance and use of partial water changes with a good quality reef salt should help to keep phosphate low. To remove additional phosphate, use of Phosphate Remover in your filter or add Anti-Phos liquid regularly to instantly remove phosphate.
- 【 ACCURATE LIQUID DROP TESTS 】: All NT Labs water testing kits are liquid drop tests from a dropper bottle to ensure the drops are the same size. This method of testing is significantly more precise compared to using dip strips. The use of liquid reagents guarantees accurate and dependable results for each parameter, simplifying the process of monitoring and maintaining ideal water conditions in your aquarium.
- 【 SUITABLE FOR ALL AQUARISTS 】: The ease of use of NT Labs Test Kits means they are perfect for use by beginners and seasoned aquarists alike.
