Component B 2000ml — Aquaforest Balling KH Alkalinity Reef

Aquaforest Component B 2,000 ml — alkalinity KH for the Balling reef method

The Component B 2,000 ml is the alkalinity pillar of Aquaforest's Balling trio. Liquid ready-to-dose sodium bicarbonate solution enriched with fluorine and iodine. Its job: hold alkalinity (dKH) stable at the reef's target level despite the constant carbonate precipitation from coral biomineralization. Dosed in strictly equal shares with Component A (calcium) and Component C (magnesium), it makes up the classic Balling protocol as Aquaforest ships it.

The 2 L bottle is the handy alternative to 5 L jugs for 50-200 L reef tanks with moderate consumption. Same recipe as the standard Components 1+2+3+ — only the packaging changes.

Component B's role in Balling

• Primary alkalinity supply — bicarbonate that offsets coral KH consumption.
• Added fluorine and iodine — trace elements essential to soft corals and some symbiotic algae.
• Strictly equal dose to A and C — the protocol demands 1:1:1 balance to preserve ionic chemistry.
• KH stability is priority on SPS — the parameter most sensitive to fast swings.

Aquaforest official dosing

• Starting dose (average SPS stock): 25 ml of Component B per 100 L of tank water per day.
• Measurable effect: 25 ml in 100 L raises alkalinity by about 0.65 dKH (0.23 meq/L).
• Balance: exact same dose for Components A and C — strict 1:1:1 ratio.
• Essential spread: distribute over 24 h via dosing pump to avoid KH spikes.
• Tuning: in 5-10 % steps — never abrupt on SPS.

Official composition

• Sodium bicarbonate (NaHCO₃) — alkaline base
• Fluorine (F)
• Iodine (I)

Why choose Aquaforest at ReefSolution

• Component A 2,000 ml — the calcium to dose in strictly equal amount.
• Component C 2,000 ml — the magnesium and trace elements that closes the trio.
• Alkalinity Test Pro — the essential KH test to drive Component B dosing precisely.

Frequently asked questions

Why does Component B contain fluorine and iodine?

Fluorine enters the skeletal structure of some corals and shells; iodine is essential to the enzymatic processes of many invertebrates and to blue-violet zoa coloration. Aquaforest adds them to Component B to skip separate trace-element dosing in the standard Balling protocol.

How long does a 2 L bottle last on a 100 L tank?

At 25 ml per 100 L per day, the 2 L bottle covers 80 days (about 2.6 months). On a 50 L tank, duration doubles to 160 days. On 200 L, it drops to 40 days.

Can I dose Component B alone if alkalinity drops?

No — the protocol demands the balanced A + B + C dose. Dosing B alone unbalances calcium and magnesium downward. For a temporary KH adjustment, use a KH Plus top-up which doesn't disturb the Balling trio.
