This has me a bit baffled. I have had my Liquidator running very successfully for several seasons. Just over the past few week, I noted that it was no longer keeping up with the chlorine demand. First thought it was all the debris from recent rains. Now I notice that the chlorine bed is not going down. The water flow, as measure by the flow meter is correct. Both of the float valves are working properly. Water is clearly flowing through the tank. But no chlorine is being drawn from the bed. The bed usually drops gradually and I top it off every four or five days. It has been about 10 days and no drop.
Any ideas or similar experience? I'll probably break it down and clean everything and start it up again. But I do not see any "white stuff" around the valves and have not had problems with build up in the past. I'm sure a clean and restart will get it back to normal, but I am really curious what could stop the diffusion of chlorine out of the chlorine bed.
