2 part measuring for reef aquariums

cults3d

These are two cups, each holding precisely 2 1/2 cups and 2 3/5 cups of liquid respectively, designed specifically for preparing one gallon of a two-part additive used in reef aquariums. To use them, fill the cup to its brim and then level it off. This method is much quicker and more efficient than relying on standard measuring cups. The first cup is intended for sodium carbonate or soda ash and features an "A" label on the outside and the word "Sodium Carbonate" on the inside. The second cup is meant for calcium chloride and displays a "C" on the exterior along with the word "Calcium" written on its interior surface. Using these cups results in a more consistent two-part mixture, minimizing the margin for error.
