I have seen several posts about vacation prep, but they all discuss SWGs. I don't have an SWG, and I certainly don't want to come home to a green pool. I will only be gone 4 days. Should I use pucks? I can stand to get a little more CYA as mine is around 30 right now anyway. I don't think dumping a whole lot of bleach is the answer, so I just wanted some advice to see if I am on the right track.
