I think I've repeated myself too many times on this forum, but since people come and go, I'll do it again. My current enthusiasm for making a false bottom easily and quickly, is using Coco-Tek hydroponic slabs cut to fit the bottom. They are about 3 inches thick and quite sturdy, but since they also split horizontally, you can make them thicker, if you want. You can then simply cut out areas for ponds, or to hold the pump, etc. and go from there. You can also split it to use as a drip wall, or a background for a cork bark falls or whatever. I've become a fan of "Great Stuff" for filling in behind cork. I cover the Coco-Tek with a layer of weed cloth, then put whatever substrate and plants on top of that. The Coco-tek is rather coarse cocoanut fiber that comes in 6"X3"X36" blocks, that has been treated with a latex type substance that makes it sturdy enough to hold soil, and prevents any deterioration. It is easily cut vertically or stripped horizontally into any depth you want. Around the edges of the vivarium, between the Coco-Tek and the glass, I merely pour in some aquarium gravel to hide the Coco-Tek, although by itself, it isn't all that obnoxious. Water circulates though it freely. The weed cloth is to filter out the substrate particles so they don't clog the "false bottom."
With everything on hand, I can set up and plant a tank in a day. These photos are of a 10 gallon set up, and unfortunately, the Coco-Tek has already been covered with weed cloth. I'm not very organized about taking pictures of a process. This is more or less one day's progress. Then of course, one has to test out the water pump and let things cure, run it long enough to get rid of the foam on the waterways and do a few water changes to clear stuff up. I let plants grow, perhaps add plants, change things for a month or more before it's ready for frogs.
