It is formulated for use with reverse osmosis or distilled water, which starts at GH ≈ 0 and cannot sustain shrimp health without remineralization.\u003c\/p\u003e\n\n\u003ch3\u003eWhat GH Actually Measures\u003c\/h3\u003e\n\u003cp\u003eGeneral hardness (GH) quantifies the concentration of dissolved divalent cations — primarily calcium (Ca²⁺) and magnesium (Mg²⁺) — in your water. It is measured in degrees of German hardness (°dH) or ppm; 1 °dH ≈ 17.9 ppm. \u003cstrong\u003eGH is not the same as KH\u003c\/strong\u003e (carbonate hardness \/ alkalinity) — they measure entirely different parameters and can vary independently.
