Red Sea Seawater Refractometer — Accurate Reef Aquarium Salinity d-d aquarium Formulated with chlorella for superiorThe Red Sea Seawater Refractometer is an essential tool for accurately measuring the salinity of seawater in your reef aquarium. Unlike most hobby grade refractometers that are not specifically designed for reef aquariums, this refractometer provides precise measurements at a temperature of 25C 77F. This accuracy is crucial for maintaining optimal salinity levels, which directly impact coral growth and coloration. Many standard refractometers are
