Frequently Asked Questions


The prolonged drought and the high cost of water have many pool owners deferring regular pool maintenance to remove totally dissolved solids (TDS) from their pool water. In the past we used to be able to drain a pool every 3-5 years and take care of routine maintenance projects such as this one, but times have changed and water has become too expensive to continue this practice.

What are TDS Levels and how do they effect my pool?

TDS Levels= total dissolved solids

Typical swimming pool solids are: short carbon chains, and salts of principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates.

- 0-100: water is too pure, water will weaken plaster/grout, rust metal parts, chlorine other sanitizers have a very short effective timescale

- 100-300: water  is ideal for swimming, will not damage equipment, requires low maintenance and few chemicals

- 400-700: water begins to model plaster, requires more chemicals to treat, and leaves faint smell on skin

- 700-2500: water will model pool plaster, corrosion expected in heater/pumps, strong odor, water is cloudy

- 2500-4000 water becomes muddy, plaster is heavily modeled, eyes will burn after swimming, and skin will itch

Why Are the typical pool sanitary cleaning methods not sufficient?

Sanitized swimming pool water still contains the salts, chemicals, dust and inert organic matter left over from the cleaning process.  Traditional pool filters simply aren’t fine enough to remove these items.  As these dissolved solids build up it requires more and more chemicals to sanitize the pool, wreaking havoc on the equipment, staining tile, shorting the life of the plaster.  Pools with a high dissolved solids or TDS counts, leave the skin smelly, are hard on swimwear and lack clarity

What are the Dirty Water Negative Health Effects:

- Heavy chorlin leeches color & vitamins from hair, ages skin, burn lungs and eyes

- Heavy minerals & sulfates can irritate the skin, creating health problems

My water is tested and adjusted regularly, why is this not covered?

-SB health department is not testing for TDS, only pH and free chorine levels, the pH verifies the water won’t immediately burn the skin, and the chorine verifies nothing is living in the water.  Sulfates, heavy metals and minerals, and other negative long term particles are not regulated.
