skimmer for 33g

[Corbin]

So im gonna be getting a 33g at the end of the month, haha decided that over a 20 gallon, (its a better deal is my excuse).

im running a 5.5 right now, and no skimmer, just water changes, everything is doing great. do you think its possible to get away with this on a 33g, very lightly stocked. just a handful of inverts and a couple small damsels and mostly corals or should i invest in a skimmer?

if so anyone in van got a used one for sale
