In a five gal. tank what would a nano skimmer do? would it be worth th $.

age old debate, however if nano means small, even in regards to the skimmer, then my opinion swings towards a useless product given the nature of skimming. simple, eligant, straight to the point. i love my explanation...lol, i expect 2 browny points now.

In the way of so called "nanoskimmers" such as the nano fission skimmer, they pretty much don't work. However, if you decide to skim, AquaC does have a H.O.B. nano skimmer with the same quality as the full size models.
