Nyos® CALCIUM+ powder

Nyos® CALCIUM+ is a high purity calcium chloride. With CALCIUM+ you can raise the calcium content in your saltwater aquarium quickly and simply.

How to Dose :

Pre-mixed solution (recommend):

Mix 1000g (2.2lb) of CALCIUM+ to 2000ml (0.53 gal) of RODI Water. This solution contains 135,000 mg/l Ca (135,000 ppm Ca).

7.4ml (0.95fl oz) of this solution will increase the calcium value in a 1000L (100 gal) aquarium by approximately 10mg/l (10ppm). This is a reference value; the actual dosage amount may vary.
