Understanding ORP

The Heart of Chemical Automation

Oxidation-reduction potential - or ORP, as it is better known - is the measurement of a body of water's ability to oxidize contaminants.

Great. What does that mean?

Most simply, oxidation involved an exchange of electrons between two atoms.  The atom that looses an electron has been oxidized.  The one that gains an electron has been reduced.

While we can't see this process occurring atom-by-atom, there is ample evidence of oxidation taking place every day.

Tile Cleaner

A cleaner to clean the walls (and tiles, if applicable) of concrete, gunite, shotcrete, or fiberglass pools. This product is fairly effective for eliminating light dirt, discolorations or stains. The product is safe to mix with your pool water. But, if the pool structure (walls or floor) of any type of pool is extremely dirty, discolored or stained, then contact us for assistance.

Filter Cleaner

Filter Cleaners do not have a direct effect on water chemistry. They do, however, clean the filter, which does have a direct effect on water chemistry. Filter Cleaners can be liquid or granular. Make sure you purchase the specified Filter Cleaner for your type of filter. Then, read the instructions on the label to determine the amount to add and how it should be added.

Defoamer

An "as-needed" chemical. Defoamer is actually a rarely used chemical. Defoamer is liquid. As the name dictates, Defoamer will eliminate foam from the pool water. Defoamer is actually used more with spas (hot tubs).

Enzyme Cleaner

An "as-needed" chemical. Enzyme cleaners are liquid. Enzymes are used to breakdown and eliminate the water line (also called the water ring or scum ring) that is often seen just above the surface of the water. Products such as suntan lotions, underarm deodorants, and women's make-up, as well as body oils and dirt, can attach to the pool walls (just above the surface of the water) to cause this water line. The Enzyme cleaner will react with these products, body oils, and dirt to break them down into their simplest state-liquid-in order to eliminate the water line. Read the instructions on the label to determine the amount to add, how it should be added (most manufacturers of Enzyme cleaners recommend pouring it straight from the bottle), and other precautions. Typically, foam will appear immediately after adding an Enzyme cleaner. This foam is okay-it signals that the enzymes are reacting with the water line to break it down into the liquid state for removal. Many pool owners wisely implement an Enzyme cleaner in their routine maintenance schedule.
