Just opened our pool here in Maryland. Was a tough rainy spring. Our pool is ungrounded and 20 years old. We have a Aquarite salt system. For some reason the control panel is still reading last seasons numbers! Says the salt is 3300 but we have not added anything to it. Is there a way to reset the control panel? It has been running for 24 hours and nothing has changed. We do drain the pool 18 inches to close it. By spring it is full. Thanks for any suggestions.
