I moved into a rental house with a very neglected 440-gallon pond off the patio. (You wouldn't believe how many cigarette butts and beer bottle caps I pulled out of that pond when I cleaned it; five goldfish were still, miraculously, alive!)\n\nI'm trying to set up a bog area above it and get some decent filtration going but don't have an arm and a leg. Also I have a lot to learn still, after a year of reading.\n\nI bought two of Pond Boss 16" waterfall spillways when I happened to find them online at Lowes.com for about each. (That's right, each, everything included!) Here's the Amazon ASIN if you want to see what I'm talking about: B016BUHBLS.\n\nI'm going to use one of these to set up a waterfall into a bog area, but I'm reading now about need for a skimmer (yes, there are leaves....) and wondering if I could use the second spillway box to rig up a skimmer somehow. All you creative DIY types, what would YOU do? The pond is in an area with a lot of tree roots, so there's only once place I can possibly dig down deeply enough to put the spillway box if I do set it up as a skimmer. It seems doable to me, but I can't visualize what I need to do to make it work. Help?
