| UV - best turned off at night?
In a recent gathering among hobbyists, one friend of mine said that UV should be switched on only when there is sunlight. In the dark it is best left turned off. Is there any truth to this? and why?
Also, there was a lively discussion as to where is the best place to place the UV? Is it in the last chamber, or the 1st vortex? If I remember correctly, Maeda San of Momotaro has once advice putting the UV in the 1st chamber, even though most of us put it in the last chamber. Please comment on this, thank you. |
