Thank you for being a CircuPool CORE customer.
If you have a CORE15, you would purchase this replacement cell: CORE15 cell
If you have a CORE35, you would purchase this replacement cell: CORE35 cell
If you have a CORE55, you would purchase this replacement cell: CORE55 cell
If unsure, the label on the back of the CORE control module will have a mark in the first / second / third option under "Model" (the label text indicates the model's max gallon capacity).
If for any reason you are still unsure and can not find any of your original purchase information, our team can happily assist, please customer support.
