Duradrakon TH-Plus Hardener Salt Mixture

Hardener salt mixture to increase the total hardness

Especially recommended for shrimp, crayfish and Malawi tanks
Dissolves easily and without clouding

Dosage

Already 1.45 g / 50 l water increases the TH by approx. 1° dH

Composition

33.5 % chloride, 15.9 % calcium, 14.4 % sulfate, 5.4 % magnesium, 1.1 % potassium, 0.4% carbonate, 0.1 % trace elements, remnant: crystal water

Instructions for use

Do not directly mix with CH plus preparations, but separated from it and resolve it single as diluted as possible. This prevents the precipitation of insoluble calcium and magnesium carbonates.

Please lay out the bulk of the water in advance and dissolve TH-Plus in portions, stirring vigorously.
If, by contrast, ones lays out the salt first and then adds water, especially in smaller portions, insoluble carbonates form on account of local concentration peaks, which do not readily dissolve, even after a long time. One can use the supernatant solution, or simply add the sediment into the basin, where it usually dissolves rapidly.
