Component C 2000ml — Aquaforest Balling Magnesium Reef Salt

Aquaforest Component C 2,000 ml — magnesium and Reef Mineral Salt for the Balling method

The Component C 2,000 ml is the magnesium pillar of Aquaforest's Balling trio. Liquid ready-to-dose solution combining magnesium, Reef Mineral Salt, potassium, and boron — the trace elements that pair with calcium and alkalinity in coral skeletons and tissues. Its presence in the trio stabilizes the Ca/Mg ratio critical to blocking spontaneous calcium carbonate precipitation.

The 2 L bottle suits 50-200 L reef tanks with moderate consumption. Strictly identical formula to Component 3+ in the 5 L Components 1+2+3+ kits — only the packaging changes.

Component C's role in Balling

• Primary magnesium supply — holds the Ca/Mg ratio (~3.2) that blocks spontaneous carbonate precipitation.
• Reef Mineral Salt integrated — natural trace elements (Mg, K, I, Br, F, Ba, Sr).
• Potassium and boron — micro-nutrients specific to blue coral coloration.
• Strictly equal dose to A and B — 1:1:1 ionic balance mandatory.

Aquaforest official dosing

• Starting dose (average SPS stock): 25 ml of Component C per 100 L of tank water per day.
• Measurable effect: 25 ml in 100 L raises magnesium by about 0.38 ppm.
• Balance: exact same dose for Components A and B.
• Spread: distribute the dose over 24 h to smooth swings.
• Testing: monthly Mg check is enough for most stable tanks.

Official composition

• Magnesium (Mg) — primary mineral base
• Reef Mineral Salt (NaCl-free blend)
• Potassium (K)
• Boron (B)

Why choose Aquaforest at ReefSolution

• Component A 2,000 ml — the calcium to dose in strictly equal amount.
• Component B 2,000 ml — the alkalinity KH that completes the Balling trio.
• Component C 200 ml — the nano format if the tank is very small or as a top-up.

Frequently asked questions

Why does magnesium drop more slowly than calcium?

Magnesium contributes to coral structure but in a lower-consumption proportion than calcium. A mature SPS tank may draw only 5-10 ppm of Mg per week versus 15-30 ppm of Ca. That's why the Balling trio adds 4.5 ppm of Ca for only 0.38 ppm of Mg per dose — a ratio aligned with real consumption.

What happens if magnesium drops below 1,150 ppm?

Below 1,150 ppm, abiotic calcium carbonate precipitation accelerates — alkalinity drops abnormally, calcium reactors scale up, and KH turns unstable. Aquaforest recommends never letting Mg fall below 1,180 ppm and aiming for 1,300-1,400.

Can Component C replace a separate Reef Mineral Salt dose?

Yes — Component C already carries Reef Mineral Salt in its formula. Extra dosing only makes sense on ultra-mature SPS tanks where ICP shows a specific deficit in one trace element.
