jlk said:I've got the big hob marinelands- they have cartridges for filling with carbon plus another set of carbon pre-filled media cartridges. Up to you if you want to keep carbon or change it out for something else such as polyfill or if there's room for ceramic rings/bio balls/filter foam. I am not personally familiar with this specific filter but I think you have lots of options if you are looking for something more permanent that just needs to be rinsed in tank water on occasion.
What would you suggest I do ?
