I don’t know. It’s a Voyager Swim Pro / Hayward filter and pump. Here’s a photo of it. I think I replaced it last year or the year before. How long do they last? Last night I got in and stored it all up looking for a my eyeball and ring that holds it in. It was super murky after that but is back to its normal cloudy self. BTW my pressure gauge is broken.The roughness may be a little calcium build up that you can work on after the slam. Is this an intex style cartridge filter?
