A: This site supports Rena XP filters and the media/parts available for use with the filter so I can't really comment on a Fluval product. General maintenance is usually monthly but the best way to determine this is to test your water. Once you know the quality of your water you can increase/decrease maintenance or change your filtration setup to improve your
water quality.
