Marine reagents are the essential liquids and powders used with your test kits and dosing equipment to accurately measure and maintain key water parameters in a saltwater aquarium. They’re used to monitor things like alkalinity, calcium, magnesium, nitrate, phosphate and more, helping you keep your reef within safe, stable ranges. High-quality reagents ensure reliable test results, so you can confidently adjust dosing, water changes and filtration rather than guessing. Always follow storage and expiry guidance, and replace reagents regularly to keep your readings accurate and your marine system running smoothly.
