When my family got our new order of fish from liveaquaria.com we wanted to drip acclimate them. The only problem was that it was very hard to control the knots in the air line tubing we were trying to use to drip acclimate with. So me my brother and Dad were thinking and while my Dad was watching some hospital show he got the idea of using an IV thing that controls how many Onces or milliliters were going through the IV. So we were able to get our hands on one, and i must say the IV controller thing is one of the best, easiest things to use to drip the water at a nice slow rate. Now we dont have to worry about knots.
I really hope this helps because it sure helped my family's tank.
