I just installed an Hayward Aqua-rite SWG system with a t-15 cell. I have a variable speed pump that runs in summer 2 hours on high to operate the cleaner, and 7 hours on low just circulating. The SWG works in both speeds, but at low flow I see small bubbles coming up at the pool inlet jets. Am I losing chlorine due to low flow? Does the flow rate affect the operation of the cell? It is sensing flow in both cases and the cell is running.
