I've been starting to use Randy's recipe #1 for my mixed reef tank. Like many other folks, I have been unable to find Dow Flake anywhere around me. However, Lowes carries SafeStep Extreme 7300, which the company fact sheet lists as "pure CaCl2". I mixed my first batch today and all dissolved very well with no solid precipitates. However, while the solution remains clear, it does have a yellow tint to it.
I have uploaded a photo so you can see what I am talking about. The solution on the right is the calcium chloride. The solution on the left is the 2 part magnesium mix from BRS. There is a very clear distinction in color.
I am wondering if anyone else has experienced this. I worry it will not be safe to use. Any advice? Thanks.
