Sealutions Calcium Chloride Dihydrate 0.8 kg

Component B for calcium and carbonate hardness dosage according to the Balling method

The balling method works with the addition of sodium hydrogencarbonate and calcium chloride, which results in soluble calcium hydrogencarbonate. To compensate for the excess sodium chloride that is formed, sodium chloride-free sea salt is introduced at the same time.


Fully dissolve

147 g Sealutions Calcium chloride dihydrate
168 g Sealutions Sodium hydrogencarbonate
50 g Sealutions Mineral Salt

in every 2 l of water. Maintain the carbonate hardness by daily addition of equal quantities of the three solutions, in the range of 9 - 11° dH. From empirical observation, for a 300 l reef tank you initially require just 100 ml of each solution daily. Depending on the need you will have to somewhat increase or decrease the daily dose subsequently in order to stay within the desired target range of the CH.
