Nyos® ALKALINITY+ is a high purity sodium bicarbonate. With ALKALINITY+ you can increase the carbonate hardness in your saltwater aquarium quickly and simply.

How to Dose:

Pre-mixed solution (recommend): Mix 160g (5.64oz) of ALKALINITY+ to 2000ml (0.53gal) of RODI water. 38ml (4.8fl oz) of this solution will increase the KH in a 100L (100gal) aquarium by approximately 1°dKH (1°dKH). This is a reference value; the actual dosage amount may vary.

Dosing ALKALINITY+ powder directly: Dose in the sump or pre-mix with aquarium water.30g (0.4oz) of ALKALINITY+ will increase the KH of a 1000L (100gal) aquarium by approximately 1°dKH (1°dKH). 

We recommend measuring your alkalinity at least 2 times per week.
