Reagent refill for the Tropic Marin PO4 Phosphate Test, manufacturer article 28778. It replenishes the reagents for measuring phosphate in freshwater and marine water. This item is a refill pack, not a complete test kit.
Use only with the corresponding PO4 Phosphate Test kit and its original measuring equipment and instructions. Use the model-specific evaluation chart only where supplied for that kit. Do not substitute reagents for a Professional model. No additional measuring apparatus or complete test kit is included. Retain the equipment from your existing compatible kit.
Follow the instructions supplied with the actual refill and compatible kit, including sample volumes, reagent order, mixing and waiting times. Read results under the recommended lighting. Where the test includes a standard solution, use it as instructed to check reagent performance. Avoid contaminating bottles or mixing caps. Store tightly closed in a cool, dark place and observe the shelf-life information on the actual packaging.
For aquarium water analysis only. Keep out of reach of children. Follow the hazard labels and current safety information on the actual packaging; avoid contact with eyes and skin.
