The AESumi nano skimmer from Aqua Excel is the tiniest little foam fractionator with just about every feature you can have in a skimmer. Surface skimmer, needle wheel pump with a silencer, a bubble diffuser plate, adjustable cup height and a bubble baffle on the outflow are all baked into the AESumi nano skimmer save for a self cleaning head and auto shut off. But those features would be silly, right? Rated for up to 25 gallons (100 liters), the AESumi nano skimmer has a reduced size of 5.5 x 2.6 x 10 inches and it uses a Via610 powerhead that draws just 5 watts. The AESumi sells for $52SGD (~$40) and it may be a good choice for some nano reefers who want to go the opposite route from a Mame or Gnome Glass nano skimmer.
