I have mine just below the surface, but you can have it above. Basically you want to to cause a little bit of rippling on the water surface to aid in oxegenating the water. I found that having mine above was too noisey

also what kind of filter media do i use? i have the sponges and thats all

I'm not sure about the 303. I have a Fluval 204 which has 4 sponges, and also I've added ceramic biological media. You should get some biological media such as Fluval ceramic media, or "bio balls" (black plastic balls). These allow the good bacteria to build up on them and do your biological filtration. The sponges are there purely for "mechanical" filtration (ie, to take out any bits of waste or plant debris).
