Troubleshooting Guide

Calcium Carbonate

Crystalline deposits (scale) that can form on all under water surfaces, if the water is excessively high in calcium hardness. High pH and high total alkalinity can worsen the problem. Responsible for cloudy water conditions that may result due to water being out of balance.

Calcium Chloride

A calcium compound used to raise the calcium hardness of the water. Typically, available in granular and liquid forms. Used to raise the calcium hardness level into the 150-200 PPM range.

Calcium Hardness

A measurement of the dissolved calcium content of the water. Can be tested by various methods and is reported as PPM of calcium carbonate. Proper pool or spa water balance usually requires that the calcium hardness of soft water be raised to 150-200 PPM. Higher levels can lead to scaling or cloudy water problems and may require chemical treatment.

Corrosion

A potentially damaging condition that results from low pH (acidic) conditions. Can cause damage to surfaces and underwater metal parts. Corrosive conditions will make water more irritating and aggressive. Proper spa water chemistry or balancing helps prevent corrosion problems.

Drain Bib

A male garden-hose-style fitting to which a garden hose is connected for draining the water from a spa.

Dry Acid

(aka sodium bisulfate) A chemical used to lower the pH and total alkalinity.

Enzymes

Organic agents that hasten the natural breakdown (digestion) or decomposition of oily wastes and organic residues in pools and spas.

Filter Cycle

The programmed start time during which the spa automatically turns on to clean the water.

Filter Duration (FD)

The number of hours (0-4) the filter cycle runs per occurrence. Used in conjunction with the Filter Frequency setting to determine the total number of hours per day the filtration cycle runs.

Filter Frequency (FF)

The number of times (occurrences) per day (1-4) that the filter cycle runs.
