Does anyone have a link to videos on refilling the Tornado tank MEGA CARTRIDGES with the Fluval material? I have the set-up and it works great. Also, has anyone had experience with the Totally Wicked-eliquid.com LOW RESISTANCE ATOMIZERS both the standard and the Mega? They aren't supposed to last as long (no warranty), but they perform really well. I really am impressed with TW's Tornado tank product (the new model line).
