How much higher should the chlorine level be in a water sample taken directly from the cell (by loosening up the junction and capturing leaking water) or from water taken directly from in front of a return, when the SWG is running?
I have a Hayward Goldline Aqua Rite system with a T-15 cell sized for a 40,000 gallon pool. The SWG comparison table mentioned in several posts indicates that the cell should add 1.40 lbs. of chlorine per day. I'm doing some troubleshooting and trying to figure out if my cell is producing a normal amount of chlorine. I have the test kit with the DPD powder.
