Fritz PRO Bulk Magnesium Sulfate, 5 gal.

Fritz ProAquatics Mag Sulfate is a high quality concentrated magnesium salt that is designed to replenish magnesium in captive reef systems. Monitoring and maintaining proper magnesium levels is an important part of stabilizing water chemistry values, resulting in better coral, coralline algae and invertebrate growth and health.

Add one teaspoon (3.5 g) per 10 gallons to raise magnesium by approx. 10 ppm. Dissolve required amount in RO / DI water and slowly add to a high flow area, ideally into a sump. Re-test and repeat dose until desired level is reached. Fritz ProAquatics Mag Sulfate can be used in conjunction with Fritz ProAquatics Mag Flake to more closely match the natural ratio of seawater.

NOTE: Due to the variation of granular size, conversion between volume and weight of powdered products are approximate; as a precaution, dose less than the calculated amount and measure the effect before adding the total amount.
