My pool is about nine years old and until now I have not replaced the paper cartridges for my Starite3 filter. I cleaned them a couple of weeks ago and the paper is starting to get very frayed and it remains gungy even after a good hosing down. I have ordered new filters and will put them in this weekend. Is there anything that you need to do before putting in the new filters? Should I hose them down? Anything else to do to "condition" the filters?
