The control panel for my salt water pool system had a check cell message so I took my Hayward TurboCell T-Cell-15 to the local pool store to test. They told me it failed the test and to replace it would cost $900. I nearly fell over. Then they told me that I could convert my saltwater system to a chlorine system for a lot less money. I am looking for advice on what to do. I have searched for cells online and have found that there are several models that are a lot less expensive than $900. In fact, I didn't really find one that cost that much. First, should I convert to a chlorine system? I have only had a saltwater system and know nothing of chlorine systems. Are there advantages of chlorine other than a chlorinator costing less than a salt cell? If I stay with a saltwater system, is Blue Works a good substitute for a Hayward? How about any others? I found the cell in the picture below at saltpoolstore.com, but am not sure about it. If anyone has any advice, I would be most appreciative. I am currently using chlorine tablets in my skimmers until I can make a decision on how to go forward.
