Components Strong ABCK 4x250ml — Aquaforest Concentrated Trace Elements

Aquaforest Components Strong ABCK 4×250 ml — concentrated trace elements in economy format

The Components Strong ABCK 4×250 ml kit ships Aquaforest's concentrated trace elements in a large format for mature SPS reefs and advanced Balling setups. Same recipe as the 4×75 ml kit — A Strong (strontium, barium), B Strong (heavy metals), C Strong (iodide, fluoride), K Strong (potassium) — but with more than triple the autonomy. Added to Balling solutions prepared from calcium chloride, sodium bicarbonate, and magnesium chloride, it rounds out the classic H. W. Balling protocol with the trace elements essential to biomineralization, coral pigmentation, and invertebrate enzymatic activity.

The 4×250 ml kit targets aquarists who have already validated their trace consumption with a 4×75 ml, or who run several SPS tanks simultaneously and want to save on purchased volume.

Detailed composition of the four solutions

• A Strong — concentrated strontium and barium, added to the calcium chloride solution (Balling bottle 1).
• B Strong — heavy metals cocktail (Fe, Cu, Zn, Mn, Co, Ni, Cr), also added to the Ca bottle.
• C Strong — iodide and fluoride, added to the bicarbonate solution (Balling bottle 2).
• K Strong — concentrated potassium, added to the magnesium + Reef Mineral Salt solution (Balling bottle 3).

Official dosing

• A Strong ratio: 5 ml per liter of prepared calcium chloride solution.
• B Strong ratio: 5 ml per liter of prepared calcium chloride solution.
• C Strong ratio: 5 ml per liter of prepared sodium bicarbonate solution.
• K Strong ratio: 5 ml per liter of prepared magnesium chloride and mineral salt solution.
• Reserve for: Aquaforest notes that on new tanks, concentrated traces may be unnecessary — their relevance grows with tank maturity and consuming biomass.

Specifications

Why choose Aquaforest at ReefSolution

• Components Strong 4×75 ml — the trial format before committing to the large kit.
• Components 1+2+3+ 3×5 L — the alternative macro kit if the hobbyist doesn't prep their own Balling solutions.
• Reef Mineral Salt 5 kg — the mineral blend to add to the K Strong solution in the full protocol.

Frequently asked questions

What's the difference between Components Strong and Components 1+2+3+?

Components 1+2+3+ are macro solutions (Ca, KH, Mg) already enriched with trace elements and ready to dose. Components Strong are trace-element concentrates only, added to Balling solutions prepared manually from raw salts. Two different approaches to the same goal — Aquaforest 1+2+3+ for simplicity, Components Strong for fine control of the classic protocol.

How long does a 250 ml Strong bottle last?

At the 5 ml per liter of Balling solution ratio and typical consumption of 1 L Balling per month on a 100 L reef, a 250 ml Strong bottle lasts about 50 months — over four years per bottle.

Can Components Strong be dosed directly into the tank?

No — their concentration is calibrated for dilution into prepared Balling solutions, not for direct dosing. Direct dosing would spike trace elements (especially heavy metals) at levels potentially toxic to livestock.
