My family loves having a live Christmas Tree every year. What does a live tree need to stay alive? Water! The Base I have for the Christmas Tree has a pretty good well in it, but with a live tree, it needs to be filled at least twice a day, and four or five times a day the first few days. For years, I've been using a dipstick / funnel combo to check the water level, and refill it without having to bend over and crawl under the tree. It worked really well, especially when I had presents under the tree. I've always wanted to purchase one of the external reservoirs, but I've never seen one that I've liked. This year we're leaving for the weekend a few weeks before Christmas, so I needed one to try to keep the tree alive. Read on to see how I made one.
