The best water quality starts with the SpectraLight SL-450. Built on the same trusted UV 2.0 platform as the rest of the SpectraLight lineup, the SL-450 brings higher dose throughput in the same compact 37″ housing as the SL-400 — perfect for residential pools that need a little more headroom.
The SL-450 is matched to circulation pumps moving 55–70 GPM — typical for residential pools in the 15,000–20,000 gallon range. If your pool is larger or you want extra disinfection headroom, step up to the SL-500 or SL-550.
ICO works great. I can’t imagine my pool without it. It also helps me spend less on chemicals.
This really helps me take care of my pool. It’s simple to use and works well. I highly recommend it!
It’s very handy and works well.
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.
