hW Marinemix Plus BioElements 150 gallon mix
Not for the average hobbyist.
This salt has to be mixed by aeration, not a powerhead and was very dusty/cloudy. I called the company and they said the reason it is so "dusty" is because it is designed to be mixed to a spg. of 1.020!! They said any stronger than this and the bioelements will begin to precipitate. There were of course no instructions in the box, it appears to be imported from Germany. They said it will mix clear at 1.020 as this is the perfect spg. with their salt, I simply was not comfortable with this low of a spg. for a reef tank. They also said their salt was one of the number one choices for research institutions hence my review title.
