Original Balling Refill Set

Refill set for liquid supply of calcium and alkalinity using the Balling method

Product description

The Tropic Marin® Original Balling Refill Set is for refilling the Tropic Marin® Original Balling Liquid Set by dissolving each bag in 1.32 US-gal./ 5 l water WITHOUT WEIGHING.

The three part Balling method adds calcium chloride dihydrate (part A) and sodium carbonate/bicarbonate (part B), while the addition of sodium chloride free sea salt (part C) maintains the crucial ionic balance in the aquarium water. This balanced calcium dosage creates the best conditions for good growth of corals and coralline algae and avoids the inevitable decrease of important elements seen in two part methods.


  • Highly soluble salts in three mixtures A, B and C according to the well-known Balling method in one set for each 5 l/1.32 US-gal. solution.

  • The three part method maintains the crucial ionic balance in the aquarium water.

  • No weighing of the single components necessary.

  • The separate solutions are very stable and can be stored indefinitely.

  • Easy to use: addition of equal volumes of all three solutions.

  • Can also be used as part of the Tropic Marin® Bio-Actif System.

  • Suitable for an aquarium stocked with soft corals, LPS and SPS.

  • Easy to apply – suitable both for manual dosing and for dosing pumps.


The Tropic Marin® Original Balling Refill Set contains:

Part A: Calcium chloride dihydrate (20,000 ppm Ca)

Part B: Sodium carbonate/sodium bicarbonate (2,800 °dH/l)

Part C: Sodium chloride free sea salt (~ 3,350 ppm Mg; ~ 980 ppm K)

Application & Dosage

Each bag has to be dissolved in separate containers in 5 l/1.32 US-gal. of RO water. After that the three salt solutions can be used immediately.

Separately add equal amounts of all three solutions successively to the tank water daily (DO NOT MIX THE SOLUTIONS).

The addition of 1 fl.oz./30 ml of each solution will raise the calcium level of 10 US-gal./35 l by approx. 15 ppm and the alkalinity by 2.2 °dH.

Maximum dose: 2 fl.oz./60 ml per 10 US-gal./35 l of aquarium system volume per day.

Other product recommendations

For an additional trace element supply, we recommend the solutions K+ Elements and A- Elements from Tropic Marin®.

The very accurate, straightforward Tropic Marin® water tests KH/Alkalinity-Test Professional and Calcium/Magnesium-Combitest Professional are suited for checking the quality of the water and the essential parameters.
