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

  • 16 oz. for 2,500 gallons tank
  • 1 gal. for 20,000 gallons tank


Sulfate is an essential major component / element / ion in natural sea water (NSW).


Sulfate is found at about 2700 parts per million (ppm) at 77F / 25C at a salinity of 35 parts per thousand (ppt) or a specific gravity of 1.026.


ACP Sulfate SO4– is a unique blend of highly concentrated forms of pH balanced, bio-available, and bio-active high purity sulfate.


ACP Sulfate SO4– replaces various essential forms of sulfate that are consumed by captive marine life in their normal metabolic process. Multiple forms of essential sulfate are employed as they are found in NSW.


ACP Sulfate SO4– is ideal to maintain and accelerate coral growth along with coloration and natural health.


Maintain So4– at 2700 ppm. for sea water duplication. This is ideal for marine fish and various sea plants and algae.


Maintain SO4– at 2750-2800 ppm. for reef aquariums. Avoid adjusting magnesium over 3000 ppm.


Sulfate should be in balance with: alkalinity (carbonate hardness), calcium (Ca++), Mg++ (magnesium), K+ (potassium) and pH.


Prior to adding Sulfate SO4–, test for calcium, alkalinity and magnesium Adjust with ACP #1 # 2# ,3 if necessary.


Alkalinity must be between 6-9 or 2.14-3.21 meq/L. Calcium must be between 400-460 ppm.. Magnesium must be between 133-1350 ppm. Test for other major ions and adjust if necessary only with ACP #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 Sulfate SO4– has no ammonia, phosphates, nitrites, nitrates, silicates, heavy metals or unwanted undesirable contaminates.


ACP Sulfate SO4– is available in 16 ounce / 474 ml size that will treat 2500 US gallons / 2075 Imperial gallons / 9450 Liters of sea water.


One cap (6 ml) will raise SO4– 10 ppm. in each 25 US gallons of marine aquarium water.


ACP Sulfate SO4– is also available in 1 gallon size for treating 20,000 US gallons of marine aquarium water.
