Marine Testing covers all the kits and tools you need to regularly check key water parameters in a saltwater aquarium, from basics like salinity, pH, ammonia, nitrite and nitrate through to reef essentials such as alkalinity, calcium, magnesium and phosphate. Reliable testing lets you catch issues early, fine-tune dosing and filtration, and keep your tank stable rather than guessing. Whether you’re running a simple fish-only setup or a coral-packed reef, consistent, accurate testing is the foundation of long-term health and success.
