Keeping the Sea Smart system running means swapping out these refill cartridges before they run dry. You will notice a steady drip of the solution inside the clear casing when everything is seated correctly. These small units slip into the housing without needing any tools or messy cleanup. It is handy to keep a spare pack in the locker so you do not have to worry about mid-season outages.
