Multiple forms of bio active & bio available high purity Bromide

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


Bromide/Bromine is an essential minor component / element / ion in natural sea water (NSW).

Bromide is found at about 65 parts per million (ppm) at 77F / 25C at a salinity of 35 parts per thousand (ppt) or a specific gravity of 1.026.

Research has demonstrated that sufficient levels of Br- must be present in order for Iodide to be metabolized by captive marine organisms.

Bromide is found at 10%-35% of NSW water levels in some low priced marine salts. Therefore it is essential to fortify or supplement some brands of marine salts with Br-.

ACP Bromide Br- is a unique blend of highly concentrated forms of pH balanced, bio-available, and bio-active high purity bromide/bromine.

ACP Bromide Br- replaces various essential forms of bromide/bromine that are consumed by captive marine life in their normal metabolic process. Multiple forms of essential Br- are employed as they are found in NSW.

ACP Bromide Br- is ideal to fortify low end marine salts with this essential minor ion.

Maintain Br- at 65 ppm. for sea water duplication. This is ideal for marine fish and various sea plants and algae.

Maintain Br- at 70-75 ppm. for reef aquariums. Avoid adjusting magnesium over 80 ppm.

Br- should be in balance with: alkalinity (carbonate hardness), calcium (Ca++), magnesium (Mg++), sulfate (SO4)–, K+ (potassium) and pH.

Prior to adding Br-, test for calcium, magnesium and alkalinity. 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 1290-1350 ppm. Test for other major ions and adjust if necessary only with ACP #4 and #5.

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

ACP Bromide Br- has no, phosphates, nitrites, nitrates, silicates, heavy metals or unwanted undesirable contaminates.

ACP Bromide Br- 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 Br- 10 ppm. in each 25 US gallons of marine aquarium water.

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