Is The TDS Level In your Swimming Pool To High?

Is you pool water cloudy?  Are you seeing staining of the pool surfaces? Possibly scaling, hard water or even a salty taste?  Well, if you are experiencing these pool symptoms, there is a good chance your TDS Levels are to high. 

What is TDS in my swimming pool?
Total Dissolved Solids (TDS) is a measure of the total of all soluble substances dissolved in the water.  What that means is anything you put in the pool, such as chlorine, chemicals, large swimmer load, poor maintenance and weather can increase the TDS level.   With high build up, the TDS level increases which will result in problems. 
Below are some TDS comparisons. 
 -Distilled water or pure water has a TDS value of 0ppm
 -Drinking water has a maximum TDS value of 500ppm per the EPA standards
 -Standard fresh water swimming pools maximum recommended TDS level is 1500ppm

How often should I check the TDS level?
On average, the TDS should be checked at least once every six months. 
What should I do if the TDS level is too high?
When TDS levels become too high, it is recommended that the pool be drained and refilled or at least replace some of the pool water.  At this point, the pool has been saturated with contaminants.  Even with good chemistry the problem with persist; draining would be the best bet.  However, regular backwashing will help to prevent the TDS from rising too high.
How did my swimming pools TDS get so high?

Many things cause the TDS level to rise.  Every time you add chemicals to the water you are adding solids that will dissolve in the water.  Even if you are using liquid chemical you are adding dissolved solids.  Weather is another factor everything that blows or is washed into the pool leaves behind some form of TDS. Evaporation is another reason for the TDS level to rise.

Lastly is bather load, everybody who enters the pool leaves behind some form of TDS.

What else should I check in my pool on a regular basis?

Every couple of months you should check you conditioner level 30-80 ppm is the recommended range.  Levels over 150 ppm can adversely affect the chlorines ability to sanitize.  Chlorine levels and PH should be checked every couple of days in season and especially after a heavy bather load.  Total alkalinity should be checked weekly.  Many other things should be checked on a regular basis.  If you have a pool here in Las Vegas Call us at Rick the Pool Dude (702)445-1348 for a free chemical analysis of your pool water.
