Good water chemistry is the most basic element of reef keeping and you deserve more than blind faith to ensure that you are getting exactly what you need.
Red Sea is one of the few salt manufacturers that state on their packages an accurate, guaranteed range of all of the parameters that will be achieved when mixing our salts according to the mixing instructions.
 
We are able to achieve this as our salts are produced according to a highly controlled, small-batch production process, that guarantees both a high level of homogeneity within each batch, as well as consistency from batch to batch. The process is monitored by thorough quality control testing in our laboratory, that includes state-of-the-art ICP analysis, calibrated specifically for the unique composition of seawater.
 
The accuracy of our salt production and analysis is consistently reliable – if you follow all the mixing instructions and adjust the salinity using a correctly calibrated seawater refractometer (such as Red Sea’s REEF-SPEC Refractometer), you will be able to use your salt mix to check the reliability of your marine and reef test kits.
