Thanks. It did not take me that long. All I did was place the tank on the backside so the background was flat. I used GE silicone II and rubber gloves and spread the silicone all over the background. I then took handful after handful of aquarium gravel and placed it on the silicone and then pushed it down so it would stay on there. When I lifted the tank back up, all the excess gravel just went to the bottom of the tank. It made it easier for clean up as I used the same aquarium gravel for the substrate in the water.

It depends on the powerhead. I am using a small repto powerhead, and only needs a couple inches of water to work. The bigger you have the deeper the water needs to be. They should say on the package if it needs to be fully submersed or if it only needs to be partially under. All that I did was make the waterfall wall using Eggcrate and covered it with GS foam. Before I covered the eggcrate with GS, I made the hole for where the waterfall mouth would be and just cut a small piece of the tubing I had planned on using. This allowed me to cover the eggcrate with GS. Once it was cured, I just cut out the mouth of the waterfall where the tube was. Once I was done with the background and was ready to put in my powerhead, I took out the tube and ran the new tube from the powerhead to the waterfall. I found it is a quick, easy and nice looking way to make the waterfall.
