ASF Magnesium Reef Shots - 24 x 20ml Vials

Magnesium is the third most important element in the composition of seawater. It is essential to numerous biological processes such as photosynthesis and cell division. It is also used in the formation of the skeletons of reef organisms. Levels of 1,200-1,380 ppm are desirable to maintain a healthy environment for your corals.

Shake well before using. Standard dose: 1 vial per 200 litres (50 gallons) of seawater per week. Dose to increase concentration: 1 vial per 100 litres (25 gallons) of seawater.  A weekly change of 10-20% of the water using Reef Evolution salt is highly recommended in order to maintain optimum water quality.

When adding the product, pour gently to the current in order to obtain even distribution. Allow 5 minutes between the additions of any other product.  Do not mix different products together prior dosing. Direct contact with marine organisms should be avoided as high local concentration may be harmful.
