Well, epic fail: came home to a mildly flooded tank--the coil area was gurgling. I tried to clean it up and get it working; but nope, the flooding only got worse and worse. I didn't want to waste any more juice on this, so I just stopped messing with it. But, hey, I love the drip tip--it's working out really well on my Nautilus Mini. I suppose that's my consolation prize.
