AquaCraft Part 5 – Potassium 16 oz

Potassium is an essential major component / element / ion in natural sea water (NSW). Potassium is found at about 390 parts per million (ppm) at 77F / 25C at a salinity of 35 parts per thousand (ppt) or a specific gravity of 1.026. ACP™ Potassium K+ is a unique blend of highly concentrated forms of pH balanced, bio-available™, and bio-active™ high purity potassium.

ACP™ Potassium K+ replaces various essential forms of potassium that are consumed by captive marine life in their normal metabolic process.  Multiple forms of essential potassium are employed as they are found in NSW.

ACP™ Potassium K+ is ideal to maintain and accelerate coral growth along with coloration and natural health.

Maintain ACP™ K+ at 390 ppm. for sea water duplication.  This is ideal for marine fish and various sea plants and algae.

Maintain K+ at 405 ppm. for reef aquariums.  Avoid adjusting potassium over 430  ppm.

Potassium should be in balance with: alkalinity (carbonate hardness), calcium (Ca++), magnesium Mg++, Sulfate (SO4-) and pH.

Prior to adding ACP™ K+ Potassium, test for calcium, alkalinity, magnesium and sulfate.  Adjust with ACP™ #1 # 2#, #3, #4 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™  #4.

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™ Potassium K+ has no ammonia,  phosphates, nitrites, nitrates, silicates, heavy metals or unwanted undesirable contaminates.

ACP™ Potassium K+ 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 K+ 10 ppm. in each 25 US gallons of marine aquarium water.
