Hey I have shares in JuwelCFC said:Danio you havent fallen for that old tosh have you? The blue foam pads only need to be changed when they are litterally falling to pieces, i have the original media in a juwel Rekord 120 that has been running 5 years. The white floss pad is non biological and can be rinsed under the tap to get it really clean, the same pad can be used for a few months until it falls apart.
