I bought a wine siphon. I've always had a bitch of a time balancing my 5 gallon jugs of nutes on the edge of the tub, then trying to funnel the liquid into one gallon bottles. Now I simply put the 5 gallon jugs on a table above the one gallon empty bottle, put in the siphon, give it a pump and watch her go. Can't believe I didn't think of this years ago...
