Designed to raise the level of magnesium safely in a marine system and will not upset the ionic balance.

This concentrated supplement contains over 72,000 ppm of cationic magnesium. It is nitrate, phosphate and gluconate free.

Magnesium has an important role in keeping concentrations of calcium in the marine system. If the concentrations of magnesium drops it will be very difficult to increase the concentrations of calcium. Due to the rapid bonding of calcium and carbonates in the marine system, this is usually manifested by what is referred to as a snow storm (precipitate) upon addition of calcium or alkaline buffer. The concentration of magnesium should be maintained at 1,320 mg/L. (1,320 ppm) natural seawater concentration.

MICROBE-LIFT/Magnesium Supplement is a bio-available natural component.

MICROBE-LIFT/Magnesium Supplement does not require any pre-dissolving and is an essential element for hard and soft corals, which is normally depleted by filtration and coral absorption. Magnesium Supplement is ionically balanced for reef and marine aquaria.

It is not necessary to use more magnesium supplement than recommended to increase and maintain the concentration level.

  • Due to settling in the bottle, it is important to shake well before every use!
  • Magnesium levels should be checked in the marine system, then add MICROBE-LIFT/Magnesium Supplement at the rate of 1 mL per gallon of aquarium or reef capacity daily to bring the level between 1,250 and 1,350 ppm.
  • This will raise the level by 19 ppm on a daily basis as a regular supplement.
  • When not testing add at the rate of 2 capfuls (14 mL) per 50 gallons (189 L.) every week for all marine systems.
