AquaCraft Part 3 – Magnesium 1 gallon

Multiple forms of bio active & bio available high purity Magnesium.


Magnesium is an essential major component / element / ion in natural sea water (NSW). Magnesium is found at about 1300 parts per million (ppm) at 77F / 25C at a salinity of 35 parts per thousand (ppt) or a specific gravity of 1.026.


ACP™ Magnesium Mg++  is a unique blend of highly concentrated forms of pH balanced, bio-available™, and bio-active™ high purity magnesium. ACP™ Magnesium Mg++ replaces various essential forms of magnesium that are consumed by captive marine life in their normal metabolic process.  Multiple forms of essential magnesium are employed as they are found in NSW.


ACP™ Magnesium Mg++  is ideal to maintain and accelerate coral growth along with coloration and natural health. ACP™ Magnesium Mg++ will not alter pH or alkalinity.  Mg++ maintains the critical SO4 + Cl balance.


Maintain Mg++ at 1300 ppm. for sea water duplication.  This is ideal for marine fish and various sea plants and algae. Maintain Mg++ at 1300-1350 ppm. for reef aquariums.  Avoid adjusting magnesium over 1375 ppm. Magnesium should be in balance with: alkalinity (carbonate hardness), calcium (Ca++), SO4— (sulfate), K+ (potassium) and pH.


Prior to adding ACP™ Magnesium Mg++, test for calcium and alkalinity.  Adjust with ACP™ #1 # # 2 if necessary.

Alkalinity must be between 6-9 or 2.14-3.21 meq/L. Calcium must be between 400-460 ppm..  Test for other major ions and adjust if necessary only with ACP™ #4 and #5.

Use periodic additions of ACP™ #6, #7, #8, #9 & #10 to maintain heavily stocked reef aquaria between routine water changes.  Use ACP™ #11, Sea Safe™ when mixing new salt water.

ACP™ Magnesium Mg++ has no, phosphates, nitrites, nitrates, silicates, heavy metals or unwanted undesirable contaminates.

ACP™ Magnesium Mg++ is available in 16 ounce / 474 ml size that will treat 2500 US gallons / 2075 Imperial gallons / 9450 Liters f sea water.


One cap (6 ml) will raise Mg++ 25 ppm. in each 25 US gallons of marine aquarium water.
