Reef Mineral Salt 5 kg — Bulk NaCl-Free Salt for the Balling Method - Aquaforest

Aquaforest Reef Mineral Salt 5 kg — NaCl-free large-format Balling supplement

The Reef Mineral Salt 5 kg is the economy format of Aquaforest's sodium-chloride-free mineral blend. Dosed daily as a stock solution, it offsets the chloride added by calcium dosing and restores trace elements consumed by corals — magnesium, potassium, iodine, bromine, barium, fluorine, strontium. The 5 kg bucket targets large tanks, multi-tank setups, and frag farms running the Balling method or the Ca+ / KH+ / Reef Mineral Salt routine.

At 25 g per liter of stock solution and a daily dose calibrated on the tank's calcium consumption, a 5 kg bucket lasts multiple years on a mid-sized reef.

Ionic balance principle

• Ca dosing in Balling — each calcium dose mechanically adds chloride to the tank.
• Offset via Reef Mineral Salt — supplies Mg, K and traces WITHOUT extra chloride.
• Ocean composition preserved — the tank's ionic ratio stays close to natural seawater over time.
• Simpler alternative to ICP dosing — no need to dose each trace element individually.

Official composition

• Magnesium (Mg)
• Calcium (Ca)
• Potassium (K)
• Bromine (Br)
• Fluorine (F)
• Barium (Ba)
• Iodine (I)
• Strontium (Sr) and trace elements
• NaCl-free

Preparation and dosing

• Dissolve 25 g of salt in 1 L of RO/DI water to prepare the stock solution.
• Dose the solution at a 1:1 ratio with the tank's measured daily calcium consumption.
• Use a dosing pump for even distribution over 24 h.
• Refresh the stock solution every two to three weeks to keep it homogeneous.
• Regularly check Ca, KH and Mg to tune the dose to actual consumption.

Frequently asked questions

How long does a 5 kg bucket last on a 200 US-gal tank?

At 25 g per liter of stock solution and a typical dose of 20-40 ml/day on a 200 US-gal tank with moderate growth, a 5 kg bucket easily covers one to two years. Exact duration depends on measured calcium consumption.

Can I dose without a dosing pump?

Yes — manual dosing once a day, at a set time, works fine. The dosing pump simply spreads the dose over 24 h, which limits parameter swings. On a stable tank, the gap between the two methods is small.

Is Reef Mineral Salt compatible with the Components 1+2+3+ method?

Not needed — Components 1+2+3+ already delivers all balanced trace elements across the three bottles. Reef Mineral Salt serves when Ca is dosed separately (Ca Plus, Balling calcium chloride) and the ionic deficit needs manual offset.
