Rio Nano Skimmer

[JSTR]

I would doubt the effectiveness of this skimmer on anything over 5 gallons.

Mine is running on a 10 gallon nano cube and it does a fair job of it. Yes I will admit the remora pro does a better job but its also 6-7 times the price.

Does anyone know what the extra tube is for? Its about 4 inches in length and was just sort of "extra" in the box and doesn't seem to fit anywhere. I'm saddened to say I don't even know what half the parts are for this thing and the "manual" isn't much help

Christy that extra tube is an extention to the intake tube, not that one really needs it, I threw it out. Also I would crazy glue the impeller to the magnet shaft, it really eliminates the vibration noise these things make. And one last thing that little black plug on the inner section of the intake tube can also get thrown out as the skimmer does work better without it.
