The best spa or pool water quality starts with the SL-620 with Twin Lamps. With 200 watts of combined UV 2.0 power and built-in lamp redundancy, the SL-620 is the workhorse of the SpectraLight commercial lineup — equally at home on a 40,000-gallon residential pool or a small commercial facility.
Matched to pumps moving 175–200 GPM. For higher flow rates, step up to the SL-650 or SL-800.
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.
