Do you think it’s important to maintain salinity precisely? We’re with you. That’s why we created AccuraSea Seawater Reference Solution, the only calibration solution of its kind made from real seawater. It’s pure natural sea water micron filtered and UV sterilized then adjusted with reverse osmosis water to the standard S = 35 or conductivity of 53 mS/cm at 25°C (77°F). Use it to accurately calibrate seawater refractometers and check the accuracy of swing-arm hydrometers. You may also want to use it as a reference for test kits used to measure the concentrations of various seawater components, since it is natural seawater with the correct and well-known concentrations of all dissolved salts. Packaged in 250 ml bottles.

ReVive Coral Cleaner is a revolutionary product developed by Julian Sprung for cleansing live stony and soft corals, zoantharians, and anemones. It is a surface cleaning dip based on plant extracts. Use for all general purpose live coral cleansing, as a part of acclimation to aquariums when corals or anemones are first received, for rinsing prior to shipping, and for rinsing newly fragmented corals, such as at coral farming facilities. Used in public aquariums for cleansing medusae in jellyfish culture labs, and for cleansing cuttlefish eggs. 500 ml (16.8 fl oz) bottle.
