Well my xp3 finally died and so I have an fx5 on its way. I'm assuming it won't come with any media. So what's everyone's recommendation for media. I was just planning on moving my seachem matrix rocks from the xp3 but what about the other baskets? The tank is 125 with 5 silver dollars 1.5-2", 2 oscars 3-4", and 1 male convict 2-3". Thanks
