hey guys I bought an elite mini submersible power filter the other day for my 38 litre tank and just want to reccomend this filter to everyone. (Its just like a small version of my fluval 4 plus!) It only cost me about $20 and is waaaay better than your standard bubble filter, it also pumps 56L an hour which is quite a bit for a tiny filter (it fits in the palm of your hand). It comes with an air tube which sits out of the water and aids in tank airation. So yeah, anyone else have one of these filters? they are much reccomended by me. :lol: :lol:
