My first vertical conversion attempt

[Sunshine]

It has been a while but I finally got some work done on this tank. Here is a picture of what I have done so far I had to glue the trim back on the top and bottom of the tank because it was cracked in several places and falling off. I also painted it with black acrylic paint because for some reason there was white and yellow paint on it. For the drainage layer I got a pvc pipe and cut it into 4" sections to hold up the false bottom. I notched the bottoms of the pvc so stagnant water wouldn't build up in them. Then I measured and cut the egg crate to fit the bottom and left a space for a pool at the front of the tank. I used window screen as a substrate barrier and zip tied it to the egg crate. I am hoping to put in a waterfall, but from what I have read, unless you really know what you are doing it usually fails. I am hoping I am intelligent enough to pull it off. Then I had a piece of glass cut and siliconed it on the bottom to hold in water/substrate. I made a vent for the top using window framing and window screen and siliconed it to the top. I am wondering if I should make another small one for the bottom since the tank is so big...
