The original waterfall I'd made for my vivarium didn't work as well as I would like, so I decided make another one.
I used things I already had on hand...a large piece of styrofoam, hot glue, paint and clearcoat sealant.....
I upgraded the waterfall in my vivarium
That is really nice, are you going to put any fish or something in it?
yes, in the 'pond' area I have a cory cat and a few guppys.... in the darker area (under the soil) I have an algae eater and a small red fish (can't remember the name). The falling water provides air for the fish. I've had this vivarium operating for over a year, I just replaced the waterfall and a few plants.
On my second look I can see the fish LOL I love it
