the first one has the following in the description:
"Here is my still not fully completed, Chinese Water Dragon enclosure. The dragons are just inside it chilling out right now, They permanently move in tomorrow when I install the glass.
Started with a 120g Top Fin aquarium, then added 2.5 feet on top of it, using MDF. For a total enclosure size of 5'x5.5'x2'. I then made my ledges, and waterfall cliff out of Styrofoam, then Grouted the entire inside. Then water sealed everything inside. For some reason, grout doesn't stick fantastically to expandable foam, and it has flaked off near the waterfall

, A sharpie will take care of it
Using a Fluval U4 Filter, with a poly hose attached that pumps the water up to the bamboo pipe for my waterfall. I have about 60-70 gallons of water, using silica sand as substrate, picked it up at a pool supply store, very cheap for the amount. But make sure to wash the sand thoroughly!. I'm using just a standard Humidifier for my fog, attached a 3/4" poly hose to run into the tank. It even plays nature/cricket sounds! its awesome. I have a Mist king system, but I can't seem to get it running efficiently, I have the pump sitting above the water source, so I think that might be the issue. The water is still a bit cloudy too, Hopefully it clears up!
Now its just a matter of making it Aesthetically pleasing for us humans. I left a half in recess for another sheet of MDF on the sides and face, so They will be getting wrapped in black fabric for a nice, sheen, screwless finish.
Hmm, There are tons of little things I've done, but I think i've covered the bases, any questions just ask! Stay tuned for my Savannah Monitor Enclosure!"
The second video looks like one of the waterfalls you can find in most pet stores or on amazon:
