Hi guys
I am just setting up a new terrarium for 2 red eyed tree frogs. I have an exo terra 45x45x60 terrarium and I want to create a drip wall or waterfall. I am planning on creating a expandable foam on the back wall and one of the sides. I would like to be able to run a pipe and cover it behind the expandable foam so it trickles down the wall into a small pond or stream. Is this possible at all with a external filter? I have seen the waterfall filter/pumps but I wouldn't be able
