just got a package in the mail, it had my new little modular
surface skimmer. (for nanocubes) i gotta say this thing works great! just hold it in place, the water pressure holds it tight against the back wall, it makes your overflow into an over
flow box, skims the surface of the water great! im probably going to add a couple dabs of super glue just to hold it in place during a water change, but other than that, this thing is well worth the 8 bucks.
if you dont already have one, i reccomend it, it also makes the water level in your tank stay the same, and the only changes would be in the back return compartment, which is nice if you top off often, but could be a problem if you just top off when you notice your tank is low.
