Hey Bryan, thanks for the question. Both Reef Salt and Salinity are great salts but there are some differences, the first of which is concentration. A standard bucket of Reef Salt mixes 160 gallons at a specific gravity of 1.023-1.024. A bucket of Salinity ( granted it is a larger bucket) mixes 225 gallons at a specific gravity of 1.025-1.026. So, while a bucket of Salinity will cost more than a bucket of Reef Salt or others, if you compare it gallon to gallon it only costs a few pennies extra.
One of the other great things about Salinity is that we do include a batch analysis one each bucket. This allows you to see what is in that particular batch. After mixing the batch, we test to ensure that it is within our parameters. Once cleared, the batch is packaged and stacked on pallets in the warehouse. We then send the same sample to an independent EPA registered lab that tests the parameters again, double checking ours. These parameters, pH, Alk, Ca, Mg, and Sr, from the labs tests are then printed on labels and placed on each bucket from that batch. This makes Salinity much more precise than any other salt on the market.
Really, whether you choose Reef Salt or Salinity, I am sure you will be happy with the results. :yay:
