Water testing can be completed during your visit. Our staff can conduct the following water tests on-site: Alkalinity, Calcium, Magnesium, Phosphates, Nitrates, Nitrites, Ammonia, pH, and Salinity. Reefs Edge also provides more comprehensive testing solutions that can be sent to a lab for processing. We work with customers to track their testing parameters over time to ensure your aquarium is thriving and running at optimal conditions.
