Nope. It's just something that I came up with a while back. I cut a water bottle in half, used an exacto knife to slice holes in the bottom, added gravel in the bottom for weight, added layers of filter padding, and then the uplift tube. After all that was added in I nested the two bottle halves together which is the difficult part. It's good to go after that.
One thing I would add is that I cut enough holes in the bottom of the bottle that would allow me to breathe unrestricted through the bottle. You just have to arrange the cuts so they don't compromise the bottom of it.
