I saw this new salt in my LFS and figured I'd give it shot. My only other salts I've used were Tropic Marin Pro when I filled my first tank about 2 years ago, and then dozens of pails of Reef Crystals since then (oh and some instant ocean for QT tanks). I hadn't seen much data about this salt, so I hope this information serves the community well.
I bought the "220" gallon box, and it priced out very close to the 160g bucket or 200g box of RC. I put "220" in quotes, because it is "up to". Based on the mixing directions, 27g/Litre makes 1.020 and 31g/litre makes 1.023. If the amount of salt needed is linear, I need 35g/Litre to get to 1.026. Based on this being a 23kg box, I have 23,000 grams which would make 657.14Litres at 1.026, or 173.6 US Gallons. The salt comes in a bag inside the box.
The actual salt is a little granular, not like a fine powder or even sugar or salt. It seemed to dissolve well; I made about 30 gallons at 1.026 in a Brute container with a pump in the bottom and there was only a quarter sized spot in the middle on the bottom that didn't dissolve. I took about a day mixing this, as I was trying to get the 1.026 salinity right on, and was having to add a little RODI or Salt in small amounts.
I tested the big 3, Cal Alk and Mag.
Cal (Red Sea) = 510
Mag (Red Sea) = 1400
Alk (Hanna) = 3.5meq/L = 9.8dKH
So, all in all, I give this a thumbs up and will use it in my DT and Frag tanks. Even at a lower salinity, you would probably still have reasonable amounts of Cal and Alk. Thanks for reading!
