Component C 200ml — Aquaforest Balling Magnesium Nano Reef

Aquaforest Component C 200 ml — magnesium for nano reefs on the Balling method

The Component C 200 ml ships Aquaforest's Balling magnesium solution in a nano 200 ml bottle. Identical formula to the 2 L and 5 L versions — magnesium, Reef Mineral Salt, potassium, and boron — but packaged for nano reefs, frag propagation tanks, and one-off top-ups. It completes the Balling trio (A + B + C) in Aquaforest's smallest available format.

Used at the strict 1:1:1 ratio with Components A and B, it holds magnesium stable on very small reef tanks.

Which tanks fit the 200 ml

• Pico and nano reefs 20-50 L — slow consumption that would leave a 2 L sitting too long.
• Separate frag tanks — targeted dosing on a reduced volume.
• Temporary top-up — if a 2 L Component C bottle empties before A and B.
• Hobbyist testing the Balling trio before graduating to 2 L.

Official dosing

• Starting dose (average SPS stock): 25 ml per 100 L of tank water per day.
• Effect: 25 ml in 100 L raises Mg by about 0.38 ppm.
• 1:1:1 balance: same amount for Components A and B.
• Spread: distribute over 24 h via dosing pump.

Official composition

• Magnesium (Mg)
• Reef Mineral Salt
• Potassium (K)
• Boron (B)

Why choose Aquaforest at ReefSolution

• Component C 2,000 ml — the 2 L format to switch to once consumption exceeds 200 ml per month.
• Component A 2,000 ml — the calcium to dose in equal shares in the Balling trio.
• Component 3in1 500 ml — the single-bottle alternative for nanos avoiding three separate doses.

Frequently asked questions

How long does a 200 ml bottle last on a 30 L nano?

At 25 ml per 100 L per day, a 30 L nano draws 7.5 ml daily and a 200 ml bottle lasts about 26 days. For a 20 L pico, duration stretches to 40 days.

Is the 200 ml economically worthwhile vs the 2 L?

The per-ml price of the 200 ml runs higher than the 2 L. It stays relevant for very small volumes that wouldn't finish a 2 L before expiration, or for a first trial before commitment.

What if Component C runs out before A and B?

Immediately cut A and B doses to the remaining C level while waiting for restock. Dosing A + B without C drops magnesium, which unbalances the Ca/Mg ratio and eventually triggers harmful carbonate precipitation.
