I am in the process of setting up a 55g tank. I just installed a Penguin 330 power filter which will eventually be my secondary filltration system. The instructions indicate I can fill the media baskets with a media of my own. As I am new to this filter I don't understand which media I can use and is it necessary to add additional media to these baskets. In a month I will be getting an Ehiem Pro 2260 as my main filter as I am of the understanding that 2 filters are better than one.
Thanks for any info!
