The material that I received was Excellent
I re-mineralized distilled water, 5 gallons with 2.36 grams of bee shrimp mineral gh+ and the results have been outstanding; I've had 0 deaths in my caridina tank and they've been alive and happy for at least two weeks now. Highly recommended.
Bee Shrimp Mineral GH+
Arrives fast and packaged nicely. Haven't used it yet but should be good when I do.
Best stuff to re-mineralize
