As promised, here a couple pics of how I got my pothos set up in my tank.
Warning! This is NOT pretty. In fact, it is quite ghetto looking. I am sure I could make this look a lot neater with a different container, but for now it works and the pothos (the photo makes the plant look smaller than it is) keeps my nitrate very low considered it is an overstocked tank. Testing the tank water showed only 5ppm within 4 days after the last water change.
The container I used is this
I drilled close to 100 holes in it. Carefully to avoid as much cracking as possible. It just hangs inside over the back of the tank next to a filter, with the plants sticking out.
Brown algae likes to grow inside the container, so every 2 - 3 months I simply take the whole thing out and scrub the inside clean.
My fish keep the roots short
