I suspected a problem with my IC40 last summer. I cleaned the SWG with acid and it started working fine again, or so I thought. This summer we're back to lower than expected chlorine levels. Did research and found that I likely had a faulty flow meter. Replaced that and cleaned again with acid at that time....maybe a month ago. All of the diagnostics on my cell say everything is ok. All my lights are green. Shows 20% used and 80 for temp check (pool is 82). So why is my chlorine still low? The water I tested at 18 inches depth between the returns is showing 1.5ppm. I put a syringe directly on the return and it read 5ppm (to see what was coming straight out of the system). The IC40 is set at 100% and has been since I replaced the flow meter. Any more ideas or am I out of luck?
