Not that I lose sleep over this or anything. Like a lot of people around here I've switched to beads and never looked back  |
You are exactly right. 50/50 solution only needs to be applied a few times a year because the PG takes that long to evaporate; however, Xikar solution only has a very small amount of PG. In fact, Xikar would argue that their solution is proportioned perfectly so that the PG will be gone at the same time all of the water evaporates. From my experience their solution still has a little too much PG, so I use their solution a few times and switch to distilled water until it begins evaporating quickly again.
