Map of the Rio Grande River. Will Rogers once described the Rio Grande as âthe only river I know of that is in need of irrigating,â a prescient observation considering how fragmented this fabled river has become.
Low pH (acidic water) can also corrode metal parts of a pool system and damage the plaster finish. The State standard for pH is 7.2 â 8.0 (Recommended range 7.4â7.6). To lower the pH, muriatic (hydrochloric) acid must be added. It is advisable to add the desired amount of acid to a full (plastic) bucket of water before adding to the pool. (Acid introduced directly can stain the pool wall.) To raise the pH, soda ash (sodium carbonate) must be added. ALKALINITY Alkaline (basic) substances are present in all water. Within the 7.2â7.8 pH range, alkalinity exists as a bicarbonate material.
Chlorine is the chemical most often used to keep swimming pools and Jacuzzis free of bacteria that can be hazardous to humans.deally, the level of pH in the pool should be between 7 and 8; 7.4 is ideal -- this is the pH of human tears. Once the HOCl and OCl-are done cleaning the pool, they either combine with another chemical, such as ammonia, or are broken down into single atoms. Both of these processes render the chlorine harmless.
