I run my filter 24 hrs a day, I estimate i turn my pool over about 4 times per day. My PDA says my salt level is 2600 ppm, currently i have my SCG at 50%. However i have only used test strips for checking levels.
HACH Aquacheck 7 Strips
These are the only test i have currently. Any time i take my water up for testing they always say it is perfect, and generally i dont have issues ever with water chemistry.
My issue is from day one (3 years now) at night when i turn on the firber optic underwater lights i see millions of what looks like particals, almost a haze. During the day the water is absolutly clear. Also this season i have noticed more bubbles at the return jets and the slide when it is on.
This year when i started the pool up i switched to a DE subsitute that claims it filters even smaller particals than DE.
