We make it simple for you to prepare sea water in a 5 gallon or larger container without needing to measure out the salt or use a hydrometer. Each 50 gallon box of AccuraSea1 contains 10 bags of precisely weighed synthetic seawater mix that produce 4.5 gallons of seawater at a specific gravity of 1.026 or 5 gallons at 1.024. AccuraSea1 is a superior formulation with packaging that makes it simple to produce a precise seawater solution every time. At a salinity of S=35 it produces the following target parameters: calcium 420 mg/l, alkalinity 8 dKH, magnesium 1300 mg/l, strontium 8 mg/l, potassium 400 mg/l.
