Difference in bottles of Flourish
Does this sound normal? I have two 250ml bottle of flourish. I bought them both at the same time at the same store. I started using one a month or so ago and now I have just opened the second. I noticed a complete difference in the darkness or concentration of the two. My first bottle was bottle had liquid that was opaque in brown color. My second bottle is the color of beer. Now this is a drastic difference. Which one is correct? Should I see that much difference?
