An example is bore-water that could have a total alkalinity of 300 mg/L and the pH is 6.5 caused by excess carbon dioxide, thus it is NOT alkaline although it has a high total alkalinity content. pH This is a property of the water that when it is perfectly neutral, its pH is 7.

After contaminants are considered, water quality investigators look to pH, the acidity or alkalinity, of water because drinking water should be very close to neutral, 7, while pool water should register a pH that is slightly basic, between 7.2 and 7.6. Water can become harmful to humans and wildlife if the pH gets too high or too low.

For best operation, keep the pool water level in the center of the skimmer plate when pool is in use. Low water level may cause the circulation pump to lose prime resulting in pump damage. High water level reduces or eliminates the skimmers effectiveness. POOL SURFACE CARE. The bathtub ring, which forms on the pool wall or tile caused by body oils,

Copper is also added to swimming pool and aquariums to control algae and bacteria. Concentrations of 1.0 ppm or higher may give water a bitter taste and cause staining/ discoloration. The copper content of drinking water is generally below 0.03 ppm, but can be up to 0.6 ppm in some areas. Dissolved Oxygen/ Biochemical Oxygen Demand:

Pools with a capacity of 175,000 gallons or less should only receive three gallons or less of acid per 24 hour period. Again, NEVER ADD WATER TO ACID; ALWAYS ADD ACID TO WATER. When treating a pool for high alkalinity before swimming has started for the season, add acid on alternate consecutive days and allow the acid to work for 48 hours.
