My question is, where is the best place to put the media inside the filter? and what media do you recommend?
(please note I'm already running the carbon packets that they come with).
Thank you in advance.
There's alot you can do. Adding an intake sponge is probably the easiest. You can use bioballs, or biorings in the filter.
If your filter doesn't have much extra space, they also sell small pellet shaped media and little sack to put it in. You can shape that and got it in there.
Carbon isn't really needed, unless you're trying to absorb meds or some other contamination in the water, but it doesn't really hurt anything.
Sponge filters are good too.
