Marine Alkalinity Supplement 500ml

As alkalinity is continuously depleted by organic load, corals and other marine organisms, you should add Alkalinity Supplement regularly to try and maintain a level of 125 to 215ppm or 7 to 12dKH. When this level is maintained, along with calcium and strontium, it will aid in the growth of hard corals, improving the growth & strength of the bone structures formed by corals & other organisms.

Directions: Add 1ml to 100 litres of aquarium water at a time. This will raise alkalinity levels by approximately 1ppm. Always add this product into a high water flow to disperse alkalinity evenly throughout the aquarium.
