Do not mix in an aquarium containing live organisms. Do not use without mixing with sodium chloride as instructed. Do not handle with wet hands. May have a slight sulfurous odor when the container is first opened; this is a result of the use of anhydrous magnesium chloride and will dissipate.
Each ~43 g of NēoMarine Kalibrate mixed with ~91 g of non-iodized sodium chloride (NaCl) will increase the resultant specific gravity of 1 US-gallon to ~1.025 g/cm3. It is presumed that aquarists employing this method will have access to an accurate scale with which to measure the required mass of Kalibrate and NaCl. Altering the ratio of Kalibrate:NaCl will resultantly alter the concentrations of elements provided by Kalibrate in the prepared seawater, while maintaining the relative ratios of the elements; for example, increasing the mass of Kalibrate used from 43 g to 46 g per gallon prepared will change the final magnesium, calcium, potassium, and strontium concentrations from 1,288-, 413-, 398.8-, and 7.625-ppm, respectively, to ~1,378-, ~442-, ~427-, and ~8-ppm, however it should be remembered that doing so will also decrease the total volume of water that this container will treat. It is strongly recommended that water purified via reverse osmosis and/or deionization be used for seawater preparation. Allow the freshly-made seawater to mix thoroughly with a submersible pump. Always use an accurate hydrometer or (preferably) refractometer to determine the specific gravity of prepared seawater. Ensure that the water temperature matches that of the established aquarium (use a submersible heater if necessary). Allow water to mix, preferably while being aerated, until pH and alkalinity become completely stable, indicating that gas equilibrium has been achieved. It is strongly recommended that at least 24 hours of mixing be allowed to pass before adding the water to an established aquarium. This extra time enables gas formed during the salt dissolution to escape, further stabilizing pH; elevated alkalinity at the suggested ratio of Kalibrate:NaCl is often a result of insufficient mixing time. Note that water temperature and mixing rate will influence the speed with which the salt goes into solution.
The best sources of sodium chloride are “plain” or non-iodized (Kalibrate already contains the proper amount of iodide so additional iodide which would be contributed by iodized salt is not necessary), greater than 99% purity, and do not contain anti-caking agents such as Yellow Prussiate of Soda (a.k.a. “YPS”), stabilizers such as Sodium Cyanurate, buffers, or metal detoxifiers; so-called “standard pool salts” with no additives may meet these requirements and can often be purchased in 40-lb. bags for pennies per pound. Keep in mind that FCC- or Food-grade salts will have a lower percentage of insoluble materials and elements such as calcium and magnesium per unit mass than will pool salts; USP- and ACS-grade salts are even better.

When changing salt blends, it is recommended that no more than 5% of the total system volume is changed on a weekly basis for the first 3-months; this enables system inhabitants to gradually adjust to the changing water chemistry with minimal irritation. It is recommended that 10 - 20% of the total water volume in an aquarium system be replaced every 7 - 10 days; this helps maintain proper water chemistry and consequently benefits aquarium inhabitants.
