Through the chemical process known as "ion-pairing", magnesium ion concentration influences the saturation point for calcium corbonate in solution.
In general, the further the magnesium concentration drops from natural seawater levels (1350 ppm), the more difficult it becomes to maintain adequate levels of both calcium and alkalinity.
Magnesium also plays an important role in stabilizing pH by interacting with the buffer system of seawater. B-Ionic Magnesium is an easy to use one component liquid supplement which, when used with B-Ionic Calcium Buffer or kalkwasser, will not disrupt the ionic balance of closed marine aquaria.
B-Ionic Magnesium does not contain nitrates, phosphates, organics, or chelating agents. B-Ionic Magnesium contains 36,000 ppm magnesium, and one mL will raise one gallon of aquarium water by 10 ppm.

$17.00The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker® HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate.
