My water is four months old. We use the spa about five nights per week. About a week ago, my water started to get a little cloudy. I'm on the HS Freshwater system and my water is normally crystal clear. I can tell when the water doesn't respond like it normally does when it's fresh. The bubbles from my HS CD ozinator become very small any fizzy--not sure why. This is the time I normally dump the water.
Anyway, I wanted to know what my TDS readings were when this happens. Steve suggests dumping the water at 1,500 ppm. I've never checked my readings before.
I went to my local HS dealer but they don't perform any water testing. I went to Leslies but thier meter was broken.
I ended up going to another pool store and the kid behind the counter looked at me like I was crazy when I asked him if he could check my TDS levels. He brought out the manager and he used test strips for the test. My water came back at 1,500 ppm. He said that my water should be good until 3,000 ppm.
I know test strip are not totally accurate but Steve was very close on the mark here. Not sure if there's any point to this thread except that I know to dump the water at 1,500 ppm. Thanks Steve....
