I bought this Century.. it is a bit cloudy but the flow seems real nice and there are no bubbles. I plan on trying what I can to clear it. I am going to cycle first... I may try Loren's method if that doesn't work (the fog juice and glycerin method). I doubt I will take it to the filtration step since I don't want to spend a fortune on a filter... that will be my limit!
I didn't realize until it showed that it has a birthday this month. The cap says March 1974!
I started cycling and only realized after a few hours that the bulb that came with it is 60W. I shut it off and will swap in a 40W.
