This is my first year with a pool and going into the winter. I know it's bad to store bleach and muriatic acid together, but is this only if opened? Is it OK to keep two, 1 gallon, un-opened bottles of each of these in a medium-sized outdoor plastic storage bin? I have other chems in there, including 1 large bin of tabs.
Also, if anyone has a recommendation for a solid but inexpensive sump pump for an inground pool with a mesh safety cover, love to hear!
