I have a 15 gallon planted aquarium. im getting a new filter, my old one cracked and clogged up way to often. Im getting a eheim classic. What type of filter media should i get to benefit my tank the best?
you wont have filter media until pump has been running for a few weeks but as long as you don't change the water he fish won't know the difference, the filter will make up the filter media as it filters through old water.
