Remarkable. Revolutionary. Ultraviolet Disinfection.

The best spa or pool water quality starts with the SL-800 with Twin Lamps. The SL-800 is the flagship of the SpectraLight commercial line — engineered for the highest residential and commercial flow rates, with 374 GPM throughput in a single chamber.

Why operators choose UV-C sanitization

  • Destroys 99.9% of bacteria, viruses, and algae as water passes through the chamber
  • Eliminates 100% of combined chloramines — no more red eyes or chlorine smell
  • Reduces chlorine use by up to 50%, often paying for itself in chemical savings
  • Twin-lamp redundancy keeps sanitization online during lamp replacement

Engineered for the largest commercial pools

Hotel and resort pools, athletic-club lap pools, aquatic-facility leisure pools — the SL-800 is the right pick whenever flow rates push above 300 GPM. For very large or multi-pool facilities, consult our team about parallel installations.

ICO works great. I can’t imagine my pool without it. It also helps me spend less on chemicals.

I’ve used ICO for 2 years and I’m happy with it. I wish I could make a data table so I can note what I’ve done.

I wish there was a quick guide for fixing pool levels, like “add chlorine to raise ORP.” That would help a lot.

Very helpful app that goes with the ICO sensor. The info is clear. It would be nice if we could tap “OK” for simple notices (like cold water). Also, when buying a new probe, a small tool for changing it would be great.
