Technology
Salt-natural chlorine generator and automated pool chemistry controller
 Salt-natural chlorine generator Ultra-violet germicidal disinfection Solar powered mineralizer Mineral pool care Chlorine [In-line or off-line injectors, or floating dispensers]
Pool Types
Fresh water and salt water pools; indoor or outdoor
 Fresh water and salt water pools; indoor or outdoor Fresh water and salt water pools; indoor or outdoor Fresh water and salt [6] water pools; outdoor pools only [2] Fresh water and salt water pools; indoor or outdoor Fresh water and salt water pools; indoor or outdoor
How does it Work? Converts salt into safe low level chlorine; also monitors and adds acid to maintain pH level Converts salt into safe low level chlorine Instantly eliminates biological growth with ultra-violet light Converts sunlight into electricity which in turn introduces beneficial mineral ions to the water Granulated product dissolves adding metal ions and minerals to the water. Regular addition of toxic chlorine is added; super chlorination [shocking] typically required
Chemical Chlorine Reduction 100% 100% 70% or more typical [1] 80% or more typical [1] 50% 0%
Chloramine Reduction [3] 100% 100% 70% or more typical 80% or more typical 50% 0%
Water Quality Crystal clear, soft, silky; no chlorine taste or odor Crystal clear, soft, silky; no chlorine taste or odor Clear; reduced chlorine taste or odor Crystal clear water with only trace oxidizer, reduced chlorine. No bad taste or odor Crystal clear water with only trace oxidizer, reduced chlorine. No bad taste or odor Water can be murky, dull, hard; chlorine taste or odor; damage to skin, hair, equipment, clothing, etc
Chlorine and Sanitation Monitoring Automatic Automatic Manual chemical test Kit [5] Not Required Not Required Manual chemical test Kit [5]
pH Control Precision pH stabilization by automatic acid injection [4] Naturally increases pH levels - decreases normal amount of required acid; requires periodic addition of acid Requires normal addition of acid or soda ash to maintain pH level Naturally stabilizes pH - requires less acid or soda ash Naturally stabilizes pH - requires less acid or soda ash Requires normal addition of acid or soda ash to maintain pH level

[1] Manufacturer states some amount of chlorine or oxidizers typically must be added
[2] Bacquacil pools must be converted to Chlorine before unit operation
[3] Chloramine Reduction may be temporarily minimized during heavy bather load, heavy rainfall, or when adding large volumes of fresh water
[4] Must add bulk acid to the Acid Tank approximately every 3 months to maintain level in tank
[5] Not included; typical test kit used by pool owners
[6] Salt water will shorten electrode life
[7] Non-chlorine oxidizer can be used instead of chlorine with equally good results
