Sausage Posted June 5, 2003 Share Posted June 5, 2003 Does anyone have any idea how this works? http://www.sgreefclub.com/forum/index.php?...ST&f=13&t=1535& I'm interested in building my own. Does it need an air pump at all? Link to comment
skeletor Posted June 5, 2003 Share Posted June 5, 2003 looks like it may just use a venturi power head, no pump required. Link to comment
