SpectraClear SL500 (UV Light System)


UV water disinfection

UV water disinfection of private pools and spas is a chemical-free method of killing microorganisms by shortwave ultraviolet light. To ensure a safe and pleasant pool environment without using strong disinfection chemicals, ultraviolet water purification destroys organic pollutants instantly as the water passes through the treatment chamber. The ultraviolet sterilization systems for private pools are particularly suitable for users who are sensitive to the usual swimming pool disinfectants, heavy metals from ionic purifiers or allergic to chlorine.

UV water purification advantages:

  • More pleasant bathing in a very low chemical environment
  • Dramatically reduced chemical dosing (50% or more) and chemical costs
  • Possibility of zero-chlorine bathing, using peroxide disinfectants
  • Unrivalled protection against contamination in swimming pool filter media
  • Safety-net protection against loss of chemical dosing – real life tests with no dosing for a month proved the pool water still stayed fresh
  • Instantaneous water disinfection at every pass
  • Very low power consumption
  • Economical swimming pool treatment – low purchase and running costs


Where Did UV Sanitizers Get Their Start?


UV Kills Bacteria

The UV light spectrum was discovered with the identification of light waves. Scientists have known for almost a century that UV is a powerful neutralizer of algae, bacteria and viruses. UV sanitizer technology was first used to sterilize drinking water over 30 years ago. Research has proven the optimal ultraviolet wavelength to destroy microorganisms is between 250 and 270 nm. Ultraviolet disinfection gained popularity in drinking water and wastewater disinfection about 10 years ago. Now ultraviolet sanitizers disinfect a significant percentage of all drinking and wastewater. The big news is that New York City has designed the world’s largest drinking water facility, capable of treating two billion gallons per day. New York will install twelve-thousand ultraviolet lamps – the same type of lamps found in SpectraLight UV sanitizers.


Side Note from Red Square Pools

The primary purpose of UV lights is to remove excess combined chlorine (CC), normally only an issue on indoor pools. Properly installed UV lights will help reduce algae but can’t possibly eliminate algae on their own. Likewise they can provide some assistance in sanitizing the pool, but can never sanitize the pool on their own. UV lights only affect the water passing through them. The bulk of the water remains in the pool at any given moment and is thus not protected.

You have to have some sanitizer in the bulk pool water or the water is not safe to swim in. The only three EPA approved sanitizers are chlorine, bromine, and baquacil. Chlorine is usually the best choice. Bromine is good for hot tubs because it is more stable than chlorine at high temperatures. Baquacil is rather expensive and many people using baquacil report major problems after the first year or two.

    We have a 25000 gal in ground pool. Looking for an UV system but only have 110 volt out to shed. Have anything we can use?

    • Try looking at the Hayward Aqua Rite In-Ground Chlorine Generator which can be wired for either 120v or 220v.

      Turbo Cell Right-sized salt chlorination
      Hayward now offers a new line of Turbo Cells for their salt chlorination and controls solutions. The cells come in three sizes – 40,000, 25,000 and 15,000 gallons. The new sizes enable you to right-size your pool for the most-efficient and cost-effective chlorination possible. These cells are based on the proven Turbo Cell technology that made Hayward the leader in salt chlorination. They automatically generate a self-renewing supply of fresh, pure chlorine – for water that’s clean, clear and luxuriously soft. Best part is most pool stores have equipment to test it to make sure it is operating properly. This will be very important to you around year 3-5 as this is when most chlorinators will need to be replaced. ALWAYS buy the chlorinator that has the 3-Year Limited Warranty.

      We sell the 40K Gallon System for $850.00.

    Hi I have a pool 22/36 how much cost me uv sistem SL 500 ??

    • Attila,

      Great morning! Assuming your pool is an average 5.5 feet deep (8′ deep-end + 3′ shallow-end / 2 = 5.5 feet deep) I’m estimating your pool is around 33,000 gallons. The SL-500 should satisfy flow rate requirements between 30 – 60 GPM for your body of water.

    Hi, I am going to install a new pool I was thinking of going with the salt water version also using the uv spectra my question is would the two make my pool clean & algae free.Thanks

    • Barbara,

      Using UV and salt to sanitize water together in theory would kill microbial organisms and introduce oxidizer sodium hypochlorite. With both systems installed one would still need to test water weekly to make sure it is balanced. No body of water (pool and/or spa) is maintenance-free and still requires the occasional additives. The difference is you would not have to use the copious amounts of chlorine and muriatic acid every year. Before you choose to make this investment I’d recommend calling the manufacture(s) regarding compatibility.
