Best sollution I can offer you is to do weekly 5 gallon waterchanges. You will not need a skimmer and will not have to have a skimmer in or outside your tank.
I am an advocate for skimming a tank but with weekly waterchanges it's not nessecary IMO
Other benifit's to these frequent waterchanges are happy inhabitants and consistant calcium and alk levels.
cheers
