I've seen people that have done this as to protect the filter and SWG from the elements. Wondering if it's a good idea? I found a good size rubbermaid deck box on Craigslist for $100, and I'm contemplating getting it. Is it really necessary? Will it prolong the life of the filter and SWG? If it's just for looks, I probably don't really care. But if it helps protect the stuff, then it's probably a worthy investment.
