Just had pool , spa, and fountain remodeled/refinished with pebble tech two weeks ago. Chemical start us was done and currently the pool and waterfall which are on one system testing good with Taylor test kit for correct levels. However, spa which is app 300 gallons shows no chlorine when I test. Test water looks a little cloudy but no pink. Tried 3 scoops and still nothing. Don’t know what pool guy did during his part of the startup but don’t understand the no chlorine reading. Have not been in any of the water and the heater has not been turned on. Ph levels are ok and only need minor adjustments in pool and spa. Alkalinity ok. Calcium ok. Oh, did I forget to mention the water in the spa is crystal clear! What’s up with that chlorine reading?
