REMEDIATION OF HIGH TDS

In order to protect your pool equipment, especially heaters, from the damages of high TDS we test and monitor readings monthly.  We notify management when readings are high and schedule pool/spa draining/filling to alleviate the problem.  By being vigilant regarding Total Dissolved Solids, we protect your pool, equipment and swimmers and save you thousands in unnecessary damages to plaster, equipment and heaters.

What is TDS?

Do you ever wonder why your pool water may begin to look dull and not as sparkly as it once did? It might be due to your total dissolved solids. 

One of the most overlooked concepts in pool water chemistry is the measure of total dissolved solids. Your total dissolved solids, or TDS, value is the measure of the sum of all the substances dissolved in your pool water. Freshwater swimming pools should have a maximum TDS value of around 1,500 to 2,000 ppm. For example, drinking water can have a maximum TDS value of 500 ppm according to the EPA. TDS meters are readily available and can be purchased online at very reasonable prices. 

The TDS Problem

Virtually everything that is added to the pool contributes to an increase in the TDS value including chlorine, shock, algaecides, clarifiers, pH remediation products, etc. Even bather-introduced contaminants such as hair care products, body lotions, deodorants, sweat, URINE, etc. can significantly add to TDS levels. Another TDS concern for outdoor facilities includes any lawn care or landscaping chemicals that may inadvertently find their way into the pool. Evaporation of pure water from pools can also leave behind a higher concentration of TDS over time.

Chlorides and sulfates as TDS in your pool can cause problems such as reducing chlorine efficacy, dulling pool water clarity and allowing algae to bloom. High levels of phosphates and nitrates can consume chlorine and also help algae bloom.

High TDS Indications

If you repeatedly have problems maintaining the proper chlorine levels, water clarity or your pool water has a salty flavor – even though the water is properly balanced, sanitized and filtered – you might have a problem with TDS. High TDS as a result of dissolved metals can also result in staining of pool surfaces. 

High calcium-based TDS can result in scaling, both on pool surfaces and in pump room equipment, which can shorten the service life and lead to costly repairs. As TDS levels begin to exceed the 2,000 ppm range, the risk of galvanic corrosion also increases due to the concentration of dissimilar metals within the system.  (Clear Comfort; 9/27/2019)
