Better Tasting PLUSThe 3M™ Whole House Water Treatment Media PHPLUS is packaged as six 4 lb./1.8 kg bottles per case and is used in the maintenance of both Residential and Commercial water treatment products when used in conjunction with MC-050P chemical-free iron reduction media. In chemistry, pH is a numeric scale between 0 and 14 used to specify the acidity or alkalinity (base) of an aqueous solution. Solutions with a pH less than seven (7) are acidic, solutions with a pH greater than seven (7) are base and solutions with a pH of seven (7) being neutral. Pure or distilled water is considered neutral, being neither acidic nor basic. Examples of everyday items and their pH levels are: battery acid has a pH rating of approximately 1.0 (very acidic) while bleach has a pH rating of around 13.0 (high levels of alkaline). Common indicators of high pH are bitter taste, water pipes and water using appliances and fixtures become encrusted with deposits, and it depresses the effectiveness of disinfection of chlorine, thereby causing the need for additional chlorine to be used. Low pH water will corrode or dissolve metals and other substances such as piping, which can then lead to water leaks.
