Hey loans_n_fishes,
Back in the day when I was trying to cut corners on my first nano, I purchased the very same (visi-jet-ps) skimmer. I don't mean to ruin a possible sale, but that skimmer did not work at all. I ended up using the pump that came with it for circulation and trashing the rest. The skimmer is meant to go inside the aquarium and looks more like an eye-sore than anything. It also tends to dump a whole lot of microbubbles back into the tank because of the way it is set up (water gets pumped back into the tank from the bottom of the skimmer). Just my $0.02......
