I have been using 6 Taifun GTs almost exclusively for the last few months with horizontal micro coils. Every time I rewick them, I wonder what is the best length to leave the wicks stick out the sides. Long, pressing on the tank, or flush not touching the tank wall?


Back to my make shift capillary action lab:

Remember those quartz tubes we experimented with a while back to encapsulate a wick? I took 6 three inch tubes and threaded cotton, hemp, and ramie thru them. PITA. I left 3mm of wick sticking out the bottom. I then placed one of each type in a jar with the end of the wick resting on the bottom and the other three just off the bottom of the jar. Added juice to the jar.

Results:
All the wicks that were off the bottom wicked faster and higher than their equivalent wicks resting on the bottom. As an added test I cut the wicks of the "off bottom" flush with the quartz tubes and the results were the same.


Conclusion:
You get better wicking (capillary action) when the end cross section of the wick is exposed to the juice and not if it is resting on the tank surface. So now I cut all my Taifun GT wicks flush so they do not press against the tank.:)
