Refill Aquahometest Ca+Mg

This is the reagent refill kit for the Fauna Marin AquaHomeTest Ca+Mg kit, restocking the titration solutions used to measure calcium and magnesium in reef aquarium water.

• Measures calcium across approx. 300-498 mg/l and magnesium across approx. 820-1800 mg/l
• Resolution: approx. 4 mg/l (Ca) and 20 mg/l (Mg) per titration step
• Reagent refill only — sufficient for approx. 50 additional tests
• Reuse your existing AquaHomeTest vial, syringes, and color comparator

Calcium and magnesium need to stay in a tight, balanced ratio for coral skeleton growth. Testing only pays off if you keep testing, and a reagent refill is the affordable way to keep running the full AquaHomeTest kit instead of buying a whole new box once the original solutions run low.

Includes: replacement Solutions A, C, and D for the AquaHomeTest Ca+Mg kit (vial, syringes, and comparator not included — reuse your existing kit hardware).

Caution: Solution A may irritate skin and eyes. Solution D contains ammonia and sodium hydroxide and may cause severe burns and eye damage. Solution C contains lead nitrate. Keep away from children.
