don't be, it's a very good question, i think false bottoms are better for long term tanks. i have gravel in a lot of my temp. tanks. for larger tanks false bottoms are more economical too. but for a 10 gallon it's just a little more $$$ for gravel. flse bottoms are nice cause you can put filters, water heaters, and water pumps for water falls under them. this is almost impossible with just gravel. also, even if you're not using any water heaters, filters... they seem to keep the humidity up more than just gravel, not really sure why, but they do. here's how to make one:
Step one: The first thing you want to do is put 3-4 inches of black silicone around the base of the tank. This is to hide the PVC. Let this sit for 24-36 hours before doing anything else.
Step two: The next step is to put the PVC in. The diameter of the PVC depends on the size tank you are building and what you plan to do with it. Cut the piping so it is between one and three inches high (most of the time they will do this for you at the place where you bought it) and silicone them to the bottom of the tank with clear silicone.
Step three: After the PVC is in place you put the egg crate over it. If you want to have a water area then have the PVC gradually get smaller to make a slope leading to the water area. Then if you plan to make a waterfall insert the pump closest to where the water will be. It is important to put the tubing of the pump through the egg crate so it is visible. If you have sloped the PVC for a water area then slope the egg crate there too.
Step four: Then put screen over everything. This is to prevent substrate such as dirt from clogging the pump.
Step five: You have the basic foundation laid out, now you just need to add substrate, plants and herps. My suggestion for the first layer of substrate is to use either large river rocks or pebbles, on top of this put either moss or dirt. Live moss is the best to use because it does not deteriorate like dirt and does not mold. It also will not get caught in the pump. Then put all the décor in as needed. If you had done a pump put the plastic tubing through the substrate(s) where you plan to have the water come out of.
