So I got a hold of a bucket of the highly anticipated Salinity, the first of three buckets currently available on the Central Coast! Here's what Seachem says about it:
"salinity™ is a blend of salts specifically formulated for the reef aquarium that contains all essential major, minor, and trace components found in natural reef waters, but contains no toxic or non-essential components. Additionally, salinity™ is the most concentrated salt blend on the market. With a hydration level of <0.5% salinity™ will yield a greater volume of prepared saltwater at a salinity of 35‰ per unit of weight than any other salt mix currently on the market.
salinity™ is identical to the distribution of anions and cations found in Natural Sea Water (NSW). We have compiled data from all the oceans and seas on the Earth, and have targeted the midpoint of the range for each element. We guarantee to be within ± 3% of the midpoint."
First impression- this bucket is HEAVY! And huge, at least 5 gallons. Second impression, it is VERY dry, almost like powdered sugar.
Each bucket is stickered with the guaranteed values of 19 elements, including lab-certified results for each batch for the "big 4" (ph, Alk, Calcium, Magnesium) and Strontium.
There is a surprisingly detailed list of mixing instructions also, but once you cut through the excess it is straight-forward.
It is slightly more concentrated then other mixes, using slightly less then 1/2 cup per gallon (for my starting mix I used 7 cups for 15 gallons). They advise allowing it to mix for 24 hours to "achieve oxygen/carbon dioxide equilibrium", so tomorrow I will test to confirm the accuracy of their claims!
