Help! Piece of crap skimmer!

[mikellini]

I've heard a few bad things about this one and its big brother (NWB-150-SSS), specifically with sensitivity to water level and feeding. You can always try adjusting it to skim a bit wetter. I prefer a dry skimmate, but then this requires cleaning the neck every couple of days because the buildup reduces skimming efficiency and eventually it will just stop skimming altogether if the neck isn't cleaned. Wet skimming avoids this to some extent.
