Good Mornign nevr2late,
I think that if anything the water would aplify the Reiki energy. Also it is cleansing. LOL kind of a 2 for 1 deal. lol sorry been at work alittle to much, I work at a retail store also along with my practice. Also when i burn a white candle it seems to help me focus and i have been told that it helps to send your intentions right to the universe! I hope that helps.
Love and light, harmony
