I agree with JJ don't skimp out on a skimmer. You say you want better water quality and all a crap skimmer will do is make you think your doing your livestock a favor. I would reccomend the Innovative Marine skimmer line for a nano of your size.Yea that's why I want to get one everyone tells me it makes thing easier as far water maintenance.. Just need to find one reasonable price and that will fit in my overflow box of my jbj 30rl
You could also use the aquamaxx hob1 skimmer.
