Well, I took the suggestion from Bonnie and made a trip to Target. I
picked up an underbed storage container and a dish drainboard. Both
are clear. I used my Dremel to cut a spillover out of the front of the
large container. I placed the drainboard in front of it with about 4 "
under the container. I did a trial run to level things off and
eliminate any spillage. I then placed flat rocks over the drainboard
and used other stones to hide the plastic container. I threw a bunch
of hycaniths and water lettuce in the container to further help
camoflouge the container. I am not going to say it is the best
waterfall I've ever seen, but it looks decent and has no leaks and
should be fairly rodent proof.
