I have a 30,000 pool with DE Filter.
When I installed the RJ 45 I was not able to get a chlorine readig speaking with Don at Circu pool I discovered I had (Phosphates?) Which was the cause of the 0 chloine. I have since cleared the pool of phosphates and have ran the SWG for 4 days and still no Chlorine reading. What is going on? I need Help
