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