Mineral
Substances such as Calcium, Manganese, Magnesium, Nickel, Copper, Silver, Zinc, Iron, Cobalt or Aluminum. Their presence in high non-chelated concentrations can lead to stains or scale formation. The measure of water hardness is dependent on these minerals.

Non-Chlorine Shock
A granular form of potassium peroxymonosulfate (potassium monopersulfate, potassium permonosulfate), used to oxidize materials such as microorganisms, contaminants (ammonia, nitrogen, swimmer waste, oils, etc.) or chloramines.

Organic Waste
Refers to the soap, deodorant, suntan lotion, body oils, sweat, spit and urine that are introduced into the water by swimmers, as well as the leaves, dust and insects that end up in the pool. The organic waste may form undesirable chloramines, which require large amounts of chlorine or non-chlorine shock to be destroyed.

Oxidation
The burning up or destruction of organic waste and organic compounds in the pool water.

Oxidizer
Any compound that removes or destroys organic waste and organic compounds in the water.
