for the skimmer,
def. take out the blue media stuff.
i went with a aqua c skimmer instead of this one because with the aqua c, the box is tinted black/smoke colored which means you wont see all the grime and gunk in it. with the clear one, you will see it. so make sure u keep that background on! LOL
the tank looks great with the light on there, you will be happy with those.
for the ligth, check out red sea fish... google it or put 3w's infront and dotcom after it
the 13W should work nicely on the cheato..
btw, its listed under micro aquariums and accessories.
