I did the same as toad paparazzi, PVC pipe elbows, eggcrate, fiberglass mesh/screen, substrate. If you want step by step pics, just mention it and I'll link them up .

I do have a tank with hydroballs in a mesh bag I sewed. It works ok, but the water does get stinky sometimes and I have to do a total flush through when siphoning. I also still have to change the substrate a bit often, unlike the false eggcrate bottom, which I only change the top layer of about every 6 months.

I only have to siphon the eggcrate about every 2 to 4 months depending on how much I spray. I created a trap door for this. It's easy.

The hydroballs are a quick set-up, but if you're going to have live plants, I would recommend the false bottom. I'd also recommend some nice springtails and wood lice to help clean your tank and minimize mold growth. They do a great job.
