For the past few months, I have been switching back and forth around every other week or so, between my assortment of tanks like the Kanger Sub-Tank's / Kayfun's & etc.....and my assortment of drippers like my Zane's / Hanna's / Tohb's & etc....and I have come to the conclusion that dripping is in fact saving me juice. Not a whole lot, but definitely enough to notice. Of course my little experiment was not a controlled experiment though. But I do think that dripping is "my" best bet to save. Has anyone else tried this yet, and what was your conclusion?
